** Added LT and TT in the studies.
17
*** The systematic uncertainties due to the scanning of missing mass cuts and the effects of the radiative tail have been evaluated for the Q² = 0.38 GeV² data.
18
*** I calculated the RMS of the variation in SigL and SigT for all eight cuts that were scanned, and also compared them with the standard cut. attachment:Q1MMpiCutStudy_June27_24.ods
19
*** I turned off the radiative tail flag in the SIMC input files for all the kinematics of the Q² = 0.38 GeV² data, and then compared the SigL and SigT values. attachment:Q1RadiativeStudy_June27_24.ods

** 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
321
*** 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.
322
** SIMC Aerogel/HGCer geometric cuts were implemented.
323
** Particle Subtraction Script was updated. Just need pion samples from Ali.
324
** Beginning Unsep-xsect Systematic Studies
325
** Continued issues with generating new parameterization
326
*** 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.
335
** 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.
336
** SIMC HMS DC resolution (suggested by Dave G.) doesn't make a huge difference.
337 710 Ali Usman

** SIMC Weight
348
*** 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. 
349
** SIMC MM
350
*** 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.
351
** MM PID Analysis
352
*** Played around with MM cuts to see PID of leak through/higher K+ channels.
353
*** Increasing aerogel cut from aero > 3.0 to > 4.5 should resolve some of the issues, but more probably needs to be done.
354
** MM cut: Yield Comparison
355
*** 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.

375
** Issues with dummy runs
376
*** The dtype error for some dummy runs was caused by empty trees when applying the CT cuts.
377
*** 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.
378
** Weird t-distribution
379
*** Multiple peaks seen in the t-distribution were caused by various particle leakthrough.
380
*** 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.
381
** Fixed binning issue
382
*** Issue with the binning script was causing many average kin per bin values to be zero. 
383
*** The scripts were completely rewritten and things look very nice now.
384
** Separated Xsects Script
385
*** Finished debugging the script that separates the cross section. 
386
*** The binning issue was hiding other FORTRAN related issues, in particular, with the input files that are generated.
387
** SIMC MM
388
*** Very broad and long tail on kaon MM generated by SIMC. Still under investigation.
389
** SIMC High Q2
390
*** There were negative MM and other variables being generated by SIMC for high Q2 settings.
391
*** Likely caused by sigT going negative. By setting some of sigT's parameterization to zero, the issue should be resolved. Still under investigation.

** 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.

** SIMC code was updated to match what is in hcana, using hcana and parts of Carlos' code as a template. Things do not look right though. 
1047
** We are a month behind at this point and Bill has finally responded to my questions so I am going to fully concentrate on getting cross sections before the Hall C collaboration meeting in January so that Nathan can present them. I am setting a soft deadline of January 6th to get him early results but will continue to push for cross sections by the talk.

** Plots of right/left/center for each physics setting have been added, including efficiencies and t-bin plots (no diamond cuts yet!). These plots show the input to Bill's code for comparison. These need to be updated with Ali's updates so a new set of replays will need to be analyzed.

** 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.
1091
** 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.

** 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.

1138
** 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.
1139
** 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.
1171
*** It should be noted, there are huge discrepancies between BCM4A and BCM1 in some cases (like 20+ uA).
1172
** Ran into some issues with the cross-section code. I am in debug mode trying to find the cause.
1173
** 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.
1191
** 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 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.

1537
** 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.

*** Tighter cuts and cuts on timing, beta, etc. will be needed for cleaner electron cuts
1766

** 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.
1823
*** Richard will pick up looking at the HGCer calibrations from Vijay's scripts. 
1824
*** Richard will also be looking at the SHMS calorimeter and with the suggestion of getting some negatively polarized SHMS runs from Hem.
1825
** The HMS Cherenkov is finished with the conclusion that the calibrations from the online runs are good
1826
** We can begin looking forward towards efficiencies. 
1827
*** Garth suggested that looking at PID may be an advantageous first steps. Precise definitions of these PIDs will need to be logged.

1881
** Extra peaks in HG from cross-talk and "ghost-bands" due to ADC screw up

*** cuts applied on SHMS ADC ref time amplitude (greater than zero) done before any further event selection and histogram filling
1883
** This is a temporary fix to "ghost-bands" and cross talk
1884
*** Although for HG there is still a small peak. The hodoscope is fine.
1885
** The time window is easier to set now.
1886
** DC has been fine (since it uses TDC)
1887
*** DC calibrations should be good to complete, other detectors need more fixes (i.e. the remaining "ghost-band")

1891

1892 1 Richard Trotta
** Two major issues...
1893 67 Richard Trotta
## Amplitude goes to null and integral is low or negative which causes a rate-dependent efficiency. 
1894 1 Richard Trotta
*** Peter has used the average pulse value acquired over a large sample of runs for each detector. 
1895 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)
1896
*** Peter created a routine to find the best offset by means of matching TDC and ADC
1897
** Richard has been checking for bugs in the code. 
1898
*** It seems to be ready to implement, Richard emailed Peter for confirmation on the implementation in our group directory

** 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
2041
** 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)
2081
** Tracking-based analysis for Runs 1415-1423, .. for now focus on HMS, typical HMS S1X rates are <
2082
** Cuts applied: PID for electrons (Cer, Cal), acceptance (delta)
2083
** Efficiency calculation was investigated in detail and applied using scalers from trees
2084
** Results for carbon (normalized to 30uA) show large variation - need to understand
2085
** *Next steps:*
2086
*** Double check calculation of computer lifetime, look for differences in TRIG and PRETRIG scalers
2087
*** Check stability of pre-scale (Ryan saw changes within runs)
2088
*** Check if detector calibrations for runs are implemented correctly
2089 1 Richard Trotta
*** Analyze with Ryan's cuts
2090 35 Stephen Kay
2091
* Luminosity Scans April 2018 (Ryan)
2092
** Confirms Richard's earlier finding that scaler-based analysis is not reliable and that it's best to analyze event-by-event
2093
** Tracking-based analysis for runs 2073-2095
2094
** Cuts applied: PID for electrons (TOF, Cal, Chi2), acceptance (delta and angles), BCM4a
2095
** Included most recent detector calibrations in replay of these runs
2096
** Efficiencies from report file mainly, may need to update tracking efficiency implementation
2097
** Found that calculations of computer deadtime requires different set of scalers for runs from January to those from April 2018
2098
** Results show carbon yields consistent with unity within error (0.5% error bars), and boiling for hydrogen and deuterium
2099 5 Richard Trotta
** *Next steps:*
2100 35 Stephen Kay
*** Check tracking efficiency
2101
2102 1 Richard Trotta
* *Global comments on Luminosity Scans (so far)*
2103 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.
2104
** Efficiencies in report files need to be updated, e.g. CPU deadtime (Richard)
2105
** Check if BCM4a is the one closest to the target - get a map of the hall (Richard, Ryan)

* eK+ coincidence time from SIDIS Spring 2018 run (Samip)
2111
** Worked with Mark Jones on coincidence time calculation - now available in hcana (see Samip's 10 May 2018 email for more details)
2112
** runs used in this analysis: 3423 with Q2=3.1 GeV2 and W=2.78 GeV
2113
** Coincidence time spectrum shows peak separations >2 ns corresponding to different accelerator frequency
2114
** Missing mass spectra: Kaon peak clearly visible, also see pions even after cuts
2115 1 Richard Trotta
** Found that pions appear localized in phase space - seems to be due to end point in kinematic phase space
2116 2 Richard Trotta
** *Next steps:*
2117 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)
2118
2119
* Yield normalized ratios from SIDIS (Hem)
2120
** Yield ratios of data to MC match well in shape, but normalization seems not quite right
2121 4 Richard Trotta
** *Next steps:*
2122
*** Check if efficiencies, currents, run time etc. are taken into account correctly

* Discussion luminosity scan analysis (earlier scan) - Richard
2131
** 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
2132
** Notes on efficiencies in report file:
2133
*** DT (EDTM) is not electronic deadtime. Instead use for now 50ns* trigger rate for HMS and 100ns* trigger rate for SHMS
2134
*** Cherenkov efficiency seems low (check if that is due to PID, thresholds, pi/e, etc)
2135
*** Tracking efficiency needs to be checked
2136
*** 3/4 trigger efficiency seems ok
2137
* Discussion luminosity scan analysis (later scan) - Ryan

* SIDIS analysis - Hem
2142
** Shown is a data/MC comparison for different kinematic settings. Agreement in shape is very good. Normalization has yet to be applied.
2143
** Discussion about agreement in z and apparent offset - relation of this offset with spectrometer offset
2144
* Analysis of exclusive events in SIDIS - Samip
2145
** Shown is a look at the first kaon events in exclusive limit of SIDIS data
2146
** Ongoing work on implementing coincidence time into tree
2147
* Discussion of run plan, and in particular possible low Q2/low energy
2148
** Assume that kaon low Q2=0.4 already included - have kinematics with specified beam energies, if needed
2149
** 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
2150
** Garth will put this together in a draft email

* Brief description of Samip's work - working on coincidence timing decoding with JLab staff and re-optimization of kinematics
2171
* Discussion of Richard's slides on run plan kinematics and preparations -
2172
** 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
2173
** 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
2174
** for each setting will need 1-2 shifts for calibrations - need to negotiate with other experiments in run group
