** 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. 
27
** 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.

** A new subroutine has been added for the hcana variable calculations in SIMC, this is ongoing.
45
** 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.
46
** Bill is doing a write-up with some questions I had which will hopefully fix the remaining issues I've been having with his code.

** 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.
71
** 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.
72
** I found a script for raster calibrations. The script is being fixed as it is currently a bit of a mess.

** 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.

** 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%.
118
** 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.
119
** 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.
151
*** It should be noted, there are huge discrepancies between BCM4A and BCM1 in some cases (like 20+ uA).
152
** Ran into some issues with the cross-section code. I am in debug mode trying to find the cause.
153
** 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.
171 390 Richard Trotta
** 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.
224
** 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. 
225
** 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 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.

517
** 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.

745
*** Tighter cuts and cuts on timing, beta, etc. will be needed for cleaner electron cuts
746
*** 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.

802 1 Richard Trotta
** 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.
803 71 Richard Trotta
*** Richard will pick up looking at the HGCer calibrations from Vijay's scripts. 
804
*** Richard will also be looking at the SHMS calorimeter and with the suggestion of getting some negatively polarized SHMS runs from Hem.
805
** The HMS Cherenkov is finished with the conclusion that the calibrations from the online runs are good
806
** We can begin looking forward towards efficiencies. 
807
*** Garth suggested that looking at PID may be an advantageous first steps. Precise definitions of these PIDs will need to be logged.
808
*** Clear notes on efficiencies steps will be needed. They will need to be redefined multiple times in multiple ways.

843
*** Richard has emailed Peter about the issue with no response yet (follow-up soon)
844
** 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.

* SHMS Reference Time Amplitude Cuts(Stephen)
861
** Extra peaks in HG from cross-talk and "ghost-bands" due to ADC screw up
862
*** cuts applied on SHMS ADC ref time amplitude (greater than zero) done before any further event selection and histogram filling
863
** This is a temporary fix to "ghost-bands" and cross talk
864
*** Although for HG there is still a small peak. The hodoscope is fine.
865
** The time window is easier to set now.
866
** DC has been fine (since it uses TDC)
867
*** DC calibrations should be good to complete, other detectors need more fixes (i.e. the remaining "ghost-band")
868
** 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)
871 67 Richard Trotta
** Peter implemented changes to hcana
872
** Two major issues...
873 1 Richard Trotta
## Amplitude goes to null and integral is low or negative which causes a rate-dependent efficiency. 
874 67 Richard Trotta
*** Peter has used the average pulse value acquired over a large sample of runs for each detector. 
875 1 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)
876 67 Richard Trotta
*** Peter created a routine to find the best offset by means of matching TDC and ADC
877
** Richard has been checking for bugs in the code. 
878
*** It seems to be ready to implement, Richard emailed Peter for confirmation on the implementation in our group directory
879
880 1 Richard Trotta
* Calibration of HMS detectors when the timing is agreed upon by Stephen and Richard.
881 67 Richard Trotta
** Besides hodoscope which still has an issue with the script
882 65 Richard Trotta
** Stephen and Richard are having a meeting late next week to determine time window values
883 62 Richard Trotta
*** These will be relatively final, but on the wider side if adjustments need to be made in the future

* Richard
1020
** 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
1021
** 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 (Richard, Ryan)
1036 111 Richard Trotta
** Carbon scan from April seems consistent with no boiling, LH3 and LD2 show deviation from unity, should check effect of EDTM events on efficiencies
1037 35 Stephen Kay
** Carbon scans from January (low rates) have large deviations from unity, in particular behavior at higher currents (>40uA), e.g. cpu dead time, that is not yet understood
1038
** discussion about pre-scale factors
1039 1 Richard Trotta
1040 35 Stephen Kay
* Discussion about Richard's script extracting and printing information from report files and trees including histograms

* Luminosity Scans January 2018 (Richard)
1061
** Tracking-based analysis for Runs 1415-1423, .. for now focus on HMS, typical HMS S1X rates are <
1062
** Cuts applied: PID for electrons (Cer, Cal), acceptance (delta)
1063
** Efficiency calculation was investigated in detail and applied using scalers from trees
1064
** Results for carbon (normalized to 30uA) show large variation - need to understand
1065
** *Next steps:*
1066
*** Double check calculation of computer lifetime, look for differences in TRIG and PRETRIG scalers
1067
*** Check stability of pre-scale (Ryan saw changes within runs)
1068
*** Check if detector calibrations for runs are implemented correctly
1069
*** Analyze with Ryan's cuts
1070 1 Richard Trotta
1071 35 Stephen Kay
* Luminosity Scans April 2018 (Ryan)
1072
** Confirms Richard's earlier finding that scaler-based analysis is not reliable and that it's best to analyze event-by-event
1073
** Tracking-based analysis for runs 2073-2095
1074
** Cuts applied: PID for electrons (TOF, Cal, Chi2), acceptance (delta and angles), BCM4a
1075
** Included most recent detector calibrations in replay of these runs
1076
** Efficiencies from report file mainly, may need to update tracking efficiency implementation
1077
** Found that calculations of computer deadtime requires different set of scalers for runs from January to those from April 2018
1078
** Results show carbon yields consistent with unity within error (0.5% error bars), and boiling for hydrogen and deuterium
1079
** *Next steps:*
1080 5 Richard Trotta
*** Check tracking efficiency
1081 35 Stephen Kay
1082
* *Global comments on Luminosity Scans (so far)*
1083 1 Richard Trotta
** 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.
1084 35 Stephen Kay
** Efficiencies in report files need to be updated, e.g. CPU deadtime (Richard)
1085
** Check if BCM4a is the one closest to the target - get a map of the hall (Richard, Ryan)
1086
** Uncertainties on current
1087
** Detector calibrations
1088 1 Richard Trotta
** HMS vs. SHMS
1089 35 Stephen Kay
1090
* eK+ coincidence time from SIDIS Spring 2018 run (Samip)
1091
** Worked with Mark Jones on coincidence time calculation - now available in hcana (see Samip's 10 May 2018 email for more details)
1092
** runs used in this analysis: 3423 with Q2=3.1 GeV2 and W=2.78 GeV
1093
** Coincidence time spectrum shows peak separations >2 ns corresponding to different accelerator frequency
1094
** Missing mass spectra: Kaon peak clearly visible, also see pions even after cuts
1095
** Found that pions appear localized in phase space - seems to be due to end point in kinematic phase space
1096 1 Richard Trotta
** *Next steps:*
1097 2 Richard Trotta
*** Look for a run with kaon momentum closer to 3 GeV/c (aerogel threshold is ~3 GeV/c for kaons for n=1.015)
1098 35 Stephen Kay
1099
* Yield normalized ratios from SIDIS (Hem)
1100
** Yield ratios of data to MC match well in shape, but normalization seems not quite right
1101
** *Next steps:*
1102 4 Richard Trotta
*** Check if efficiencies, currents, run time etc. are taken into account correctly

* Discussion luminosity scan analysis (earlier scan) - Richard
1111
** 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
1112
** Notes on efficiencies in report file:
1113
*** DT (EDTM) is not electronic deadtime. Instead use for now 50ns* trigger rate for HMS and 100ns* trigger rate for SHMS
1114
*** Cherenkov efficiency seems low (check if that is due to PID, thresholds, pi/e, etc)
1115
*** Tracking efficiency needs to be checked
1116
*** 3/4 trigger efficiency seems ok
1117
* Discussion luminosity scan analysis (later scan) - Ryan
1118
** Fewer carbon runs than earlier scan
1119
** Shown is a tracking-based analysis using data from the ROOT trees
1120 111 Richard Trotta
** First results for carbon, LH3, and LD2, but efficiencies need to be checked
1121 35 Stephen Kay
* SIDIS analysis - Hem
1122
** Shown is a data/MC comparison for different kinematic settings. Agreement in shape is very good. Normalization has yet to be applied.
1123
** Discussion about agreement in z and apparent offset - relation of this offset with spectrometer offset
1124
* Analysis of exclusive events in SIDIS - Samip
1125
** Shown is a look at the first kaon events in exclusive limit of SIDIS data
1126
** Ongoing work on implementing coincidence time into tree
1127
* Discussion of run plan, and in particular possible low Q2/low energy
1128
** Assume that kaon low Q2=0.4 already included - have kinematics with specified beam energies, if needed
1129
** 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
1130
** Garth will put this together in a draft email

1148 18 Richard Trotta
1149 35 Stephen Kay
*  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.
1150
* Brief description of Samip's work - working on coincidence timing decoding with JLab staff and re-optimization of kinematics
1151
* Discussion of Richard's slides on run plan kinematics and preparations -
1152
** 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
1153
** 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
1154
** for each setting will need 1-2 shifts for calibrations - need to negotiate with other experiments in run group
1155
** kinematics plots W-Q2 show that still need to do some optimization
1156
** run sheets: include raster size, update coincidence count labeling, and carbon target labeling
1157
* Discussion of next meeting. Garth at JLab 8-16 March - might have meeting during that time.
