** 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.

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
202
*** 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.
203
** SIMC Aerogel/HGCer geometric cuts were implemented.
204
** Particle Subtraction Script was updated. Just need pion samples from Ali.
205
** Beginning Unsep-xsect Systematic Studies
206
** Continued issues with generating new parameterization
207
*** 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.
216
** 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.
217
** SIMC HMS DC resolution (suggested by Dave G.) doesn't make a huge difference.
218 710 Ali Usman
** The resolution of MC looked worse than data after t-bining. This will be improved with a lower multiplication factor.

** SIMC Weight
229
*** 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. 
230
** SIMC MM
231
*** 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.
232
** MM PID Analysis
233
*** Played around with MM cuts to see PID of leak through/higher K+ channels.
234
*** Increasing aerogel cut from aero > 3.0 to > 4.5 should resolve some of the issues, but more probably needs to be done.
235
** MM cut: Yield Comparison
236
*** Using an MM cut of 1.10 < MM < 1.18 produced shockingly consistent yields for Q2=2.115

** 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.

256
** Issues with dummy runs
257
*** The dtype error for some dummy runs was caused by empty trees when applying the CT cuts.
258
*** 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.
259
** Weird t-distribution
260
*** Multiple peaks seen in the t-distribution were caused by various particle leakthrough.
261
*** 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.
262
** Fixed binning issue
263
*** Issue with the binning script was causing many average kin per bin values to be zero. 
264
*** The scripts were completely rewritten and things look very nice now.
265
** Separated Xsects Script
266
*** Finished debugging the script that separates the cross section. 
267
*** The binning issue was hiding other FORTRAN related issues, in particular, with the input files that are generated.
268
** SIMC MM
269
*** Very broad and long tail on kaon MM generated by SIMC. Still under investigation.
270
** SIMC High Q2
271
*** There were negative MM and other variables being generated by SIMC for high Q2 settings.
272
*** 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.
286
** Equations for the xsect iteration script have been properly adjusted to match those found in the fortran script of SIMC (physics_iterate.f).
287
** 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. Data and SIMC comparison look very good for W distribution but doesn't perfectly match for missing variables.

** 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.
1020
** 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.
1052
*** It should be noted, there are huge discrepancies between BCM4A and BCM1 in some cases (like 20+ uA).
1053
** Ran into some issues with the cross-section code. I am in debug mode trying to find the cause.
1054
** Tanja sent me some awesome fpi2 raster correction documents as well as procedures for verifying the beam and target positions. I am in the process of reading through/beginning these procedures. A Redmine wiki page will be linked when completed.

** 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.
1072
** 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.
1125
** 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. 
1126
** 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.

1418
** 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.

** The "tasks":https://redmine.jlab.org/projects/kltexp/wiki/Analysis_Tasks page has been updated with a section for efficiencies. 
1689
*** 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.
1704
*** Richard will pick up looking at the HGCer calibrations from Vijay's scripts. 
1705
*** Richard will also be looking at the SHMS calorimeter and with the suggestion of getting some negatively polarized SHMS runs from Hem.
1706
** The HMS Cherenkov is finished with the conclusion that the calibrations from the online runs are good
1707
** We can begin looking forward towards efficiencies. 
1708
*** Garth suggested that looking at PID may be an advantageous first steps. Precise definitions of these PIDs will need to be logged.
1709
*** Clear notes on efficiencies steps will be needed. They will need to be redefined multiple times in multiple ways.

* Timing update (Stephen)
1738
** Reference times between Richard and Stephen are very similar and the GitHub is updated accordingly
1739

* Peter's hcana code (Richard and Stephen)
1743

1744
*** Richard has emailed Peter about the issue with no response yet (follow-up soon)
1745
** This means we still need the reference time amplitude cut with Peter's code but using just the amplitude cut with Mark's latest version of hcana should be sufficient for calibrations.

1752
*** This is the rough deadline we made for finishing up calibrations. 
1753

* SHMS Reference Time Amplitude Cuts(Stephen)
1762
** Extra peaks in HG from cross-talk and "ghost-bands" due to ADC screw up
1763
*** cuts applied on SHMS ADC ref time amplitude (greater than zero) done before any further event selection and histogram filling
1764
** This is a temporary fix to "ghost-bands" and cross talk
1765
*** Although for HG there is still a small peak. The hodoscope is fine.
1766
** The time window is easier to set now.
1767
** DC has been fine (since it uses TDC)
1768
*** DC calibrations should be good to complete, other detectors need more fixes (i.e. the remaining "ghost-band")
1769
** 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)
1772
** Peter implemented changes to hcana
1773 1 Richard Trotta
** Two major issues...
1774 67 Richard Trotta
## Amplitude goes to null and integral is low or negative which causes a rate-dependent efficiency. 
1775 1 Richard Trotta
*** Peter has used the average pulse value acquired over a large sample of runs for each detector. 
1776 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)
1777
*** Peter created a routine to find the best offset by means of matching TDC and ADC
1778
** Richard has been checking for bugs in the code. 
1779
*** It seems to be ready to implement, Richard emailed Peter for confirmation on the implementation in our group directory
1780 1 Richard Trotta
1781 67 Richard Trotta
* Calibration of HMS detectors when the timing is agreed upon by Stephen and Richard.
1782 65 Richard Trotta
** Besides hodoscope which still has an issue with the script
1783 62 Richard Trotta
** Stephen and Richard are having a meeting late next week to determine time window values
1784
*** These will be relatively final, but on the wider side if adjustments need to be made in the future

** 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
1922
** 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)
1962
** Tracking-based analysis for Runs 1415-1423, .. for now focus on HMS, typical HMS S1X rates are <
1963
** Cuts applied: PID for electrons (Cer, Cal), acceptance (delta)
1964
** Efficiency calculation was investigated in detail and applied using scalers from trees
1965
** Results for carbon (normalized to 30uA) show large variation - need to understand
1966
** *Next steps:*
1967
*** Double check calculation of computer lifetime, look for differences in TRIG and PRETRIG scalers
1968
*** Check stability of pre-scale (Ryan saw changes within runs)

** Tracking-based analysis for runs 2073-2095
1975
** Cuts applied: PID for electrons (TOF, Cal, Chi2), acceptance (delta and angles), BCM4a
1976
** Included most recent detector calibrations in replay of these runs
1977
** Efficiencies from report file mainly, may need to update tracking efficiency implementation
1978
** Found that calculations of computer deadtime requires different set of scalers for runs from January to those from April 2018

1984 35 Stephen Kay
** April 2018 scans show hydrogen and deuterium target boiling on level of 3-4%, Carbon is consistent with no boiling, as expected - based on description, new targets are expected to have less boiling than those used previously, e.g. in FPI2. Double check this.
1985

1993
** runs used in this analysis: 3423 with Q2=3.1 GeV2 and W=2.78 GeV
1994
** Coincidence time spectrum shows peak separations >2 ns corresponding to different accelerator frequency
1995
** Missing mass spectra: Kaon peak clearly visible, also see pions even after cuts
1996 1 Richard Trotta
** Found that pions appear localized in phase space - seems to be due to end point in kinematic phase space
1997 2 Richard Trotta
** *Next steps:*
1998 35 Stephen Kay
*** Look for a run with kaon momentum closer to 3 GeV/c (aerogel threshold is ~3 GeV/c for kaons for n=1.015)

2014
*** DT (EDTM) is not electronic deadtime. Instead use for now 50ns* trigger rate for HMS and 100ns* trigger rate for SHMS
2015
*** Cherenkov efficiency seems low (check if that is due to PID, thresholds, pi/e, etc)

** Shown is a look at the first kaon events in exclusive limit of SIDIS data
2027
** Ongoing work on implementing coincidence time into tree
2028
* Discussion of run plan, and in particular possible low Q2/low energy
2029
** Assume that kaon low Q2=0.4 already included - have kinematics with specified beam energies, if needed
2030
** 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
2031
** Garth will put this together in a draft email

2050
*  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.
2051
* Brief description of Samip's work - working on coincidence timing decoding with JLab staff and re-optimization of kinematics
2052
* Discussion of Richard's slides on run plan kinematics and preparations -
2053
** 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
2054
** 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
2055
** for each setting will need 1-2 shifts for calibrations - need to negotiate with other experiments in run group
2056
** kinematics plots W-Q2 show that still need to do some optimization
2057
** run sheets: include raster size, update coincidence count labeling, and carbon target labeling
2058 26 Richard Trotta
* Discussion of next meeting. Garth at JLab 8-16 March - might have meeting during that time.
