** 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.

** Properly Calculated Statistical Uncertainties
266
*** 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.
267
** SIMC Aerogel/HGCer geometric cuts were implemented.
268
** Particle Subtraction Script was updated. Just need pion samples from Ali.
269
** Beginning Unsep-xsect Systematic Studies
270
** Continued issues with generating new parameterization
271
*** 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.
280
** 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.
281
** SIMC HMS DC resolution (suggested by Dave G.) doesn't make a huge difference.
282 710 Ali Usman
** The resolution of MC looked worse than data after t-bining. This will be improved with a lower multiplication factor.

** SIMC Weight
293
*** 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. 
294
** SIMC MM
295
*** 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.
296
** MM PID Analysis
297
*** Played around with MM cuts to see PID of leak through/higher K+ channels.
298
*** Increasing aerogel cut from aero > 3.0 to > 4.5 should resolve some of the issues, but more probably needs to be done.
299
** MM cut: Yield Comparison
300
*** 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.

** Issues with dummy runs
321
*** The dtype error for some dummy runs was caused by empty trees when applying the CT cuts.
322
*** 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.
323
** Weird t-distribution
324
*** Multiple peaks seen in the t-distribution were caused by various particle leakthrough.
325
*** 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.
326
** Fixed binning issue
327
*** Issue with the binning script was causing many average kin per bin values to be zero. 
328
*** The scripts were completely rewritten and things look very nice now.
329
** Separated Xsects Script
330
*** Finished debugging the script that separates the cross section. 
331
*** The binning issue was hiding other FORTRAN related issues, in particular, with the input files that are generated.
332
** SIMC MM
333
*** Very broad and long tail on kaon MM generated by SIMC. Still under investigation.
334
** SIMC High Q2
335
*** There were negative MM and other variables being generated by SIMC for high Q2 settings.
336
*** 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.
350
** Equations for the xsect iteration script have been properly adjusted to match those found in the fortran script of SIMC (physics_iterate.f).
351
** 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.

** It has been determined that employing a single set of offsets for all energies within the summer 2019 dataset does not adequately address all variables.
474 629 Vijay Kumar
** Nonetheless, the W variable exhibits a strong agreement with the SIMC for energies of 2.7 and 4.5 GeV. However, at 3.6 GeV, a slight over-correction is observed.

** 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.

** Fits for lumi scans look great for HMS across the board. SHMS no track also look pretty good but tracking still needs work. Ali has adjusted the tracking parameters in the replay which should help things. Signs of boiling are also now evident in HMS for some runs.
1036
** Odd issue with the yields going on that I need to discuss with Bill. It seems to be a cut discrepancy that is eliminating events, I may be missing a cut that he has hidden somewhere. Besides this, the cross-section code is being edited for HeeP so we can get some cross-section plots on this soon.

** 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.

** 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.
1116

** 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.
1136
** 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 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 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). 
1482
** 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.

** PID efficiency script is coming together
1710
*** Tighter cuts and cuts on timing, beta, etc. will be needed for cleaner electron cuts
1711
*** Hcal cut should be changed to cut around the mean normalized value instead of cutting above or below it only. This will assure electrons aren't lost.

** 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.
1768
*** Richard will pick up looking at the HGCer calibrations from Vijay's scripts. 
1769
*** Richard will also be looking at the SHMS calorimeter and with the suggestion of getting some negatively polarized SHMS runs from Hem.
1770
** The HMS Cherenkov is finished with the conclusion that the calibrations from the online runs are good
1771
** We can begin looking forward towards efficiencies. 
1772
*** Garth suggested that looking at PID may be an advantageous first steps. Precise definitions of these PIDs will need to be logged.
1773

1826
** Extra peaks in HG from cross-talk and "ghost-bands" due to ADC screw up
1827
*** cuts applied on SHMS ADC ref time amplitude (greater than zero) done before any further event selection and histogram filling
1828
** This is a temporary fix to "ghost-bands" and cross talk
1829
*** Although for HG there is still a small peak. The hodoscope is fine.
1830
** The time window is easier to set now.
1831
** DC has been fine (since it uses TDC)
1832
*** DC calibrations should be good to complete, other detectors need more fixes (i.e. the remaining "ghost-band")
1833

* Peter's hcana fixes for reference time (Richard)
1836
** Peter implemented changes to hcana
1837 1 Richard Trotta
** Two major issues...
1838 67 Richard Trotta
## Amplitude goes to null and integral is low or negative which causes a rate-dependent efficiency. 
1839 1 Richard Trotta
*** Peter has used the average pulse value acquired over a large sample of runs for each detector. 
1840 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)
1841
*** Peter created a routine to find the best offset by means of matching TDC and ADC
1842
** Richard has been checking for bugs in the code. 
1843
*** It seems to be ready to implement, Richard emailed Peter for confirmation on the implementation in our group directory

1847 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
1986
** 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)
2026
** Tracking-based analysis for Runs 1415-1423, .. for now focus on HMS, typical HMS S1X rates are <
2027
** Cuts applied: PID for electrons (Cer, Cal), acceptance (delta)
2028
** Efficiency calculation was investigated in detail and applied using scalers from trees
2029
** Results for carbon (normalized to 30uA) show large variation - need to understand
2030
** *Next steps:*
2031
*** Double check calculation of computer lifetime, look for differences in TRIG and PRETRIG scalers
2032
*** Check stability of pre-scale (Ryan saw changes within runs)
2033
*** Check if detector calibrations for runs are implemented correctly
2034 1 Richard Trotta
*** Analyze with Ryan's cuts
2035 35 Stephen Kay
2036
* Luminosity Scans April 2018 (Ryan)
2037
** Confirms Richard's earlier finding that scaler-based analysis is not reliable and that it's best to analyze event-by-event
2038
** Tracking-based analysis for runs 2073-2095
2039
** Cuts applied: PID for electrons (TOF, Cal, Chi2), acceptance (delta and angles), BCM4a
2040
** Included most recent detector calibrations in replay of these runs
2041
** Efficiencies from report file mainly, may need to update tracking efficiency implementation
2042
** Found that calculations of computer deadtime requires different set of scalers for runs from January to those from April 2018
2043
** Results show carbon yields consistent with unity within error (0.5% error bars), and boiling for hydrogen and deuterium
2044 5 Richard Trotta
** *Next steps:*
2045 35 Stephen Kay
*** Check tracking efficiency
2046
2047 1 Richard Trotta
* *Global comments on Luminosity Scans (so far)*
2048 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.
2049
** Efficiencies in report files need to be updated, e.g. CPU deadtime (Richard)
2050
** Check if BCM4a is the one closest to the target - get a map of the hall (Richard, Ryan)
2051
** Uncertainties on current
2052 1 Richard Trotta
** Detector calibrations
2053 35 Stephen Kay
** HMS vs. SHMS
2054
2055
* eK+ coincidence time from SIDIS Spring 2018 run (Samip)
2056
** Worked with Mark Jones on coincidence time calculation - now available in hcana (see Samip's 10 May 2018 email for more details)
2057
** runs used in this analysis: 3423 with Q2=3.1 GeV2 and W=2.78 GeV
2058
** Coincidence time spectrum shows peak separations >2 ns corresponding to different accelerator frequency
2059
** Missing mass spectra: Kaon peak clearly visible, also see pions even after cuts
2060 1 Richard Trotta
** Found that pions appear localized in phase space - seems to be due to end point in kinematic phase space
2061 2 Richard Trotta
** *Next steps:*
2062 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)
2063
2064
* Yield normalized ratios from SIDIS (Hem)
2065
** Yield ratios of data to MC match well in shape, but normalization seems not quite right
2066 4 Richard Trotta
** *Next steps:*
2067
*** Check if efficiencies, currents, run time etc. are taken into account correctly

2075
* Discussion luminosity scan analysis (earlier scan) - Richard
2076
** Shown is a scaler-based analysis using scalers from report file and from ROOT tree - the values are different, why that is has to be checked
2077
** Notes on efficiencies in report file:
2078
*** DT (EDTM) is not electronic deadtime. Instead use for now 50ns* trigger rate for HMS and 100ns* trigger rate for SHMS
2079
*** Cherenkov efficiency seems low (check if that is due to PID, thresholds, pi/e, etc)
2080
*** Tracking efficiency needs to be checked
2081
*** 3/4 trigger efficiency seems ok
2082
* Discussion luminosity scan analysis (later scan) - Ryan
2083
** Fewer carbon runs than earlier scan
2084 111 Richard Trotta
** Shown is a tracking-based analysis using data from the ROOT trees
2085 35 Stephen Kay
** First results for carbon, LH3, and LD2, but efficiencies need to be checked
2086
* SIDIS analysis - Hem
2087
** Shown is a data/MC comparison for different kinematic settings. Agreement in shape is very good. Normalization has yet to be applied.
2088
** Discussion about agreement in z and apparent offset - relation of this offset with spectrometer offset
2089
* Analysis of exclusive events in SIDIS - Samip
2090
** Shown is a look at the first kaon events in exclusive limit of SIDIS data
2091
** Ongoing work on implementing coincidence time into tree
2092
* Discussion of run plan, and in particular possible low Q2/low energy
2093
** Assume that kaon low Q2=0.4 already included - have kinematics with specified beam energies, if needed
2094
** 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
2095
** Garth will put this together in a draft email

*Links to talks->* "Andres":https://redmine.jlab.org/documents/19
2113 35 Stephen Kay
2114
*  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.
2115
* Brief description of Samip's work - working on coincidence timing decoding with JLab staff and re-optimization of kinematics
2116
* Discussion of Richard's slides on run plan kinematics and preparations -
2117
** 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
2118
** 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
2119
** for each setting will need 1-2 shifts for calibrations - need to negotiate with other experiments in run group
2120
** kinematics plots W-Q2 show that still need to do some optimization
2121
** run sheets: include raster size, update coincidence count labeling, and carbon target labeling
2122 26 Richard Trotta
* Discussion of next meeting. Garth at JLab 8-16 March - might have meeting during that time.
2123 35 Stephen Kay
