** SHMS xptar had an odd distribution. Upon further inspection, the RF cut was the cause. There is a correlation between xptar and the RF which must have a path length correction. For KaonLT data (>Q2=0.5), the RF will no longer be used.

** Model cross-sections were compared for most of the Q2s. There were several iterations which included a +0.2 term to the t-dependence of sigL. sigT now used the model from Tanja's "global analysis":https://journals.aps.org/prc/pdf/10.1103/PhysRevC.85.018202 which is coming along. Pion subtraction still needs to be incorporated and things should improve further from there.

** Properly Calculated Statistical Uncertainties
219
*** Ali and I went through and properly implemented statistical uncertainties (double-checked with Garth on Monday). This included updating HMS cerenkov and calorimeter efficiencies that needed to use a "golden singles run" to avoid contamination. A bug in the ratio per bin was fixed so that proper average ratio per bins were found.
220
** SIMC Aerogel/HGCer geometric cuts were implemented.
221
** Particle Subtraction Script was updated. Just need pion samples from Ali.
222
** Beginning Unsep-xsect Systematic Studies
223
** Continued issues with generating new parameterization
224
*** Unsep xsect fits are starting to look good, but the script to generate improved parameterization generates insane fits. Likely a change to the model is needed. In particular, sigT will need adjustments.

** Update on the SIMC resolution study for Kaon-LT 10.6 GeV data.
233
** SIMC SHMS DC resolution was tunned to have better agreement b/w data nnd MC. A large resolution multiplication factor of 9 is used. This will hopefully decrease with improvement in data resolution.
234
** SIMC HMS DC resolution (suggested by Dave G.) doesn't make a huge difference.
235 710 Ali Usman
** The resolution of MC looked worse than data after t-bining. This will be improved with a lower multiplication factor.

** SIMC Weight
246
*** In order to get Ydata/Ysimc to be even close to unity I needed to divide the SIMC weight by 10^6. I was applying the weight for the histograms but not binned data. 
247
** SIMC MM
248
*** The long radiative tail from simc MM has mostly been resolved by using the correct decay length and properly recalculating the MM using recon_hcana.
249
** MM PID Analysis
250
*** Played around with MM cuts to see PID of leak through/higher K+ channels.
251
*** Increasing aerogel cut from aero > 3.0 to > 4.5 should resolve some of the issues, but more probably needs to be done.
252
** MM cut: Yield Comparison
253
*** Using an MM cut of 1.10 < MM < 1.18 produced shockingly consistent yields for Q2=2.115

264
** The weight iteration script is working, but there is an issue with either the SIMC weight or unit charge which is causing me to include a 10^-6 factor in the SIMC weight which messes up the rest of the iteration scripts.

273
** Issues with dummy runs
274
*** The dtype error for some dummy runs was caused by empty trees when applying the CT cuts.
275
*** The source of these fails cuts was because the CT offset applied at the replay level was skipped for these runs and thus the CT peak was not where the cut expected.
276
** Weird t-distribution
277
*** Multiple peaks seen in the t-distribution were caused by various particle leakthrough.
278
*** This was cleaned up a bit by implimenting a HMS cer cut > 1.5, but there are still significant particles that need to be cleaned up.
279
** Fixed binning issue
280
*** Issue with the binning script was causing many average kin per bin values to be zero. 
281
*** The scripts were completely rewritten and things look very nice now.
282
** Separated Xsects Script
283
*** Finished debugging the script that separates the cross section. 
284
*** The binning issue was hiding other FORTRAN related issues, in particular, with the input files that are generated.
285
** SIMC MM
286
*** Very broad and long tail on kaon MM generated by SIMC. Still under investigation.
287
** SIMC High Q2
288
*** There were negative MM and other variables being generated by SIMC for high Q2 settings.
289
*** Likely caused by sigT going negative. By setting some of sigT's parameterization to zero, the issue should be resolved. Still under investigation.

** Most bad runs (i.e. those replays/analysis files that failed for various regions) for Q2=2.1 have been properly run. There are still a few outstanding runs that need to be further investigated.

** Equations for the xsect iteration script have been properly adjusted to match those found in the fortran script of SIMC (physics_iterate.f).
304
** Testing with Q2=2.1 is underway with a minor bug with efficiency calculation that needs to be resolved. Once this is done, this setting will test the xsects iteration and separated xsects scripts.

** As expected, the bifurcation seen in the CT vs beta (E=10.6) is almost non-existent when kaon PID cuts are applied. This is likely due to the lower statistics compared to what Alicia showed with pion PID. A correction should be applied regardless which will determined by the pion data.

** I think I have tracked down the odd issues with right setting that I have been seeing for most energies. I am not sure why, but it seems that something is going wrong with the replays. I tried rerunning them, but the issue has persisted. My initial guess is that it may be an issue with the TDC cuts, since the coin time distributions were looking off previously.

** Heep Coin Offset study using Peter Bosted's correction factor for HMS central momenta. The results from 8.2 and 10.6 GeV improved after applying the offset whereas 6.2 over corrects the distributions as they are already looking good with no offset.

** Regarding Ali's work on the Pc offsets at high momentum, I referenced the delta corrections I made early last year. In EPICS, the NMR did not appear to be locked and in the middle of the scan, the NMR was changed. Slide 15 has the offsets to the central momentum, Pc.

** Luminosities are looking very nice. These now include the ones Peter pointed out that were taken during SIDIS. Nearly all e-e runs are under 5%.
1036
** I have debugged all of the issues I was having with Bill's code. I am now in the process of merging the two frameworks which is mainly just making names, conventions, etc. consistent.
1037
** I have been writing up some questions for Bill next week when he presents. I'd like to also have these two frameworks pretty much merged by then.

** Fixed some issues with the luminosity scripts with updated replay and analysis script. The biggest issue was the really low beam on times which came from BCM4a being called by accident in some cases instead of BCM1.
1069
*** It should be noted, there are huge discrepancies between BCM4A and BCM1 in some cases (like 20+ uA).
1070
** Ran into some issues with the cross-section code. I am in debug mode trying to find the cause.

** Lumi SHMS tracking is still showing the trend from 9/8. It was found that the lumi replay script is not updated with many of Ali and Richard's most recent changes. These changes are being applied and a set of new replays will be done.
1089
** Bill's cross-section code is broken into two major parts. The root analysis part, which takes all the yields, uncertainties, etc., is nearly complete with the connecting ltsep framework script finishing up. The second part, where many of the final plots and cross-sections are done, is a hard-coded mess. Richard is in the process of making this more dynamic. This aspect will take more time but the root analysis part is the bulk of the analysis anyways.

** Heep Coin analysis for high Q2 KaonLT data (6.2, 8.2, 10.6 GeV beam energy) has now all the efficiencies/live times applied. The results for all 3 beam energies are looking very good. Data/SIMC ratios are agreeing very well (< 3%) and the shapes are matching up nicely. Next step is to finalize offsets for both low and high Q2 KaonLT data. Also proton absorption correction and target boiling needs to be applied.

** The 10.6 GeV heep analysis is going well but the broad momentum distributions are making offsets difficult at times.
1142
** I have decided to give a second pair of eyes to Ali's hcana vs simc calculation investigation. It is concluded that the broad peaks of the hcana are likely caused by the secondary particle calculation which is gathered from the spectrometer track info. 
1143
** Corrections to the simc pmiss components have been added to the fortran code which corrects for a minus sign that is in hcana but missing from simc.

** The currents were adjusted from 1-10 uA with little effect on the EDMTLT but proper changes to the CPULT. The replay bcm cut script developed by Sanghwa was also analyzed to see if it may be causing the issue but it had the same effects. There was also a small error in the code found where T.coin.pEDTM.tdcTimeRaw was incorrectly written as T.coin.pEDTM.tdcTime.

** I have re-run the carbon lumi runs with the changes to the replay events (i.e. All_events_NO_EDTM). The results look pretty good (within a few percent). There are still some trends I need to investigate for certain runs and I need to do the analysis for the pionLT carbon lumi data.

** I found an issue with the replay scripts used where the EDTM was not being properly registered. There is a discrepancy between two replay scripts depending on what the Decode_master is set to (i.e. ALL_events vs ALL_events_NO_EDTM). 
1435
** The explicit calculation of the prescale has hit a snag because of the differences between 6 GeV and 12 GeV. I contacted Mark Jones, who explained there are significant differences in the ADC gate between the two eras (which my own findings confirmed). I have contacted Brad for further input.

1698 1 Richard Trotta
*** Changes such as new detector classes
1699

* Stephen improved wiggles but still prevalent
1702
1703
* Richard finished HGCer calibrations, he concluded that the online parameters are sufficient
1704
** He also has been looking at SHMS calorimeter calibrations but has had issues running the scripts. Most likely a pathing issue.
1705
** The "tasks":https://redmine.jlab.org/projects/kltexp/wiki/Analysis_Tasks page has been updated with a section for efficiencies. 
1706
*** A PID efficiency script is currently being developed and hopefully should have some plots for our next meeting.

** The calibrations are nearing completion with only the HG Cherenkov and SHMS calorimeter yet to be finished. There are also smaller issues with some DC and HMS calorimeter runs.
1721
*** Richard will pick up looking at the HGCer calibrations from Vijay's scripts. 
1722
*** Richard will also be looking at the SHMS calorimeter and with the suggestion of getting some negatively polarized SHMS runs from Hem.
1723
** The HMS Cherenkov is finished with the conclusion that the calibrations from the online runs are good
1724
** We can begin looking forward towards efficiencies. 
1725
*** Garth suggested that looking at PID may be an advantageous first steps. Precise definitions of these PIDs will need to be logged.
1726
*** Clear notes on efficiencies steps will be needed. They will need to be redefined multiple times in multiple ways. 
1727

* Hem
1729 70 Richard Trotta
** Has been looking at the calorimeter as well. 
1730
** He has seen the second band in the spectra for some runs, we suggested further looks into HMS hodoscope and subsequently reference times. A recalibration will need to be performed.

1761
*** Richard has emailed Peter about the issue with no response yet (follow-up soon)

1779
** Extra peaks in HG from cross-talk and "ghost-bands" due to ADC screw up
1780
*** cuts applied on SHMS ADC ref time amplitude (greater than zero) done before any further event selection and histogram filling
1781
** This is a temporary fix to "ghost-bands" and cross talk
1782
*** Although for HG there is still a small peak. The hodoscope is fine.
1783
** The time window is easier to set now.
1784
** DC has been fine (since it uses TDC)
1785
*** DC calibrations should be good to complete, other detectors need more fixes (i.e. the remaining "ghost-band")
1786
** Hodoscope still bad but this might be because of that "ghost-band", needs to be further investigated

* Peter's hcana fixes for reference time (Richard)
1789
** Peter implemented changes to hcana
1790 1 Richard Trotta
** Two major issues...
1791 67 Richard Trotta
## Amplitude goes to null and integral is low or negative which causes a rate-dependent efficiency. 
1792 1 Richard Trotta
*** Peter has used the average pulse value acquired over a large sample of runs for each detector. 
1793 67 Richard Trotta
## Timing offset between EL-REAL and 3/4 is 130 ns which causes junk tracks at high SHMS rates (~6% of the time)
1794
*** Peter created a routine to find the best offset by means of matching TDC and ADC
1795
** Richard has been checking for bugs in the code. 
1796
*** It seems to be ready to implement, Richard emailed Peter for confirmation on the implementation in our group directory
1797 1 Richard Trotta
1798 67 Richard Trotta
* Calibration of HMS detectors when the timing is agreed upon by Stephen and Richard.

** Besides hodoscope which still has an issue with the script
1800 62 Richard Trotta
** Stephen and Richard are having a meeting late next week to determine time window values

** Discussed with Mark Jones and is cross checking his January luminosity scan analysis against Mark's. Realized that BCM calibrations (gains, offsets etc) are different - currently working on fixing that, presents current results - low curent point is ~10% below unity, discussion that this seems to indicate that BCM offsets are the issue as low current points would be most sensitive, is planning to also double-check the BCM calibration procedure - had discussion with Dave Mack at JLab
1939
** Presents a script developed for luminosity scans that determines yields for a run number input on command line. Discussion this could be good to adapt for kaon counting during experiment.

* Luminosity Scans January 2018 (Richard)
1979
** Tracking-based analysis for Runs 1415-1423, .. for now focus on HMS, typical HMS S1X rates are <
1980
** Cuts applied: PID for electrons (Cer, Cal), acceptance (delta)
1981
** Efficiency calculation was investigated in detail and applied using scalers from trees
1982
** Results for carbon (normalized to 30uA) show large variation - need to understand

1984
*** Double check calculation of computer lifetime, look for differences in TRIG and PRETRIG scalers
1985

1993
** Included most recent detector calibrations in replay of these runs
1994
** Efficiencies from report file mainly, may need to update tracking efficiency implementation
1995

** Coincidence time spectrum shows peak separations >2 ns corresponding to different accelerator frequency
2012
** Missing mass spectra: Kaon peak clearly visible, also see pions even after cuts
2013 1 Richard Trotta
** Found that pions appear localized in phase space - seems to be due to end point in kinematic phase space
2014 2 Richard Trotta
** *Next steps:*

2030
** Notes on efficiencies in report file:
2031
*** DT (EDTM) is not electronic deadtime. Instead use for now 50ns* trigger rate for HMS and 100ns* trigger rate for SHMS
2032
*** Cherenkov efficiency seems low (check if that is due to PID, thresholds, pi/e, etc)
2033
*** Tracking efficiency needs to be checked
2034
*** 3/4 trigger efficiency seems ok
2035
* Discussion luminosity scan analysis (later scan) - Ryan
2036
** Fewer carbon runs than earlier scan
2037 111 Richard Trotta
** Shown is a tracking-based analysis using data from the ROOT trees
2038 35 Stephen Kay
** First results for carbon, LH3, and LD2, but efficiencies need to be checked
2039
* SIDIS analysis - Hem
2040
** Shown is a data/MC comparison for different kinematic settings. Agreement in shape is very good. Normalization has yet to be applied.
2041
** Discussion about agreement in z and apparent offset - relation of this offset with spectrometer offset
2042
* Analysis of exclusive events in SIDIS - Samip
2043
** Shown is a look at the first kaon events in exclusive limit of SIDIS data
2044
** Ongoing work on implementing coincidence time into tree
2045
* Discussion of run plan, and in particular possible low Q2/low energy
2046
** Assume that kaon low Q2=0.4 already included - have kinematics with specified beam energies, if needed
2047
** For pion form factor and LT, have two possible settings that can use the prescribed beam energies: Q2=1.45 and 0.35 GeV2 - prioritize towards the higher Q2 as not as sensitive to offsets
2048
** Garth will put this together in a draft email

2067
*  Discussion of Andres' slides on elastic W calculation in hcana - initial issue with negative W values seems to be due to outdated information in standard.kinematics file. Additional investigation ongoing.
2068
* Brief description of Samip's work - working on coincidence timing decoding with JLab staff and re-optimization of kinematics
2069
* Discussion of Richard's slides on run plan kinematics and preparations -
2070
** everyone agrees that in general want to have as many L/T cross section separations as possible in a robust run plan balancing statistics vs. systematics
2071
** before actual run may want to do a 3D optimization in all kinematic variables to get the best possible delta(epsilon) for the L/T separations
2072
** for each setting will need 1-2 shifts for calibrations - need to negotiate with other experiments in run group
2073
** kinematics plots W-Q2 show that still need to do some optimization
2074
** run sheets: include raster size, update coincidence count labeling, and carbon target labeling
2075 26 Richard Trotta
* Discussion of next meeting. Garth at JLab 8-16 March - might have meeting during that time.
2076 35 Stephen Kay
2077
* *Action Items:*
2078
** Post slides/notes from this meeting and procedure to set up hcana in Redmine (Tanja)
2079
** Update run sheet and kinematic optimization for W/Q2 (Garth)
2080
** Circulate elastic calculations for kinematic settings (Samip)
2081
** Continue investigation of elastic data and run plan kinematics (Andres/Richard)
2082
** Test software installation instructions (Pete)
2083 32 Stephen Kay
** Draft email to JLab management about need for small angle beam pipe - need to have HMS minimum angle of less than 13 degrees for kaon L/T separations (Tanja)
