** 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.
42
*** It should be noted, there are huge discrepancies between BCM4A and BCM1 in some cases (like 20+ uA).
43
** Ran into some issues with the cross-section code. I am in debug mode trying to find the cause.
44
** 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.
62 390 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.

** 3.6 and 3.9 GeV data do NOT have the angle offsets. This has been established in the study.
112 370 Richard Trotta
** I've plotted the offsets vs SHMS central momentum. Plots are attached in the attached pdf file.
113
* Richard
114
** The 10.6 GeV heep analysis is going well but the broad momentum distributions are making offsets difficult at times.
115
** 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. 
116
** 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.

** Updated Lumi carbon plots with uncertainties. PID and current cuts need to be played around with a bit to see if they improve things (as uncertainties don't explain any boiling-type behaviors). 
357
** Some PionLT carbon runs were looked at but there are still some issues (either cut or pathing related).

*** I have gotten a rough script working for very simple runs (ie low rate, single spectrometer, calibration runs)
371
*** I am trying to expand to lumi singles runs, things get a bit more complex so I am just working out the trigger correlations

** 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). 
408
** 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.

** Issues with DC calibration for only a few runs during each run period
717
** "wiggles" in HMS calorimeter calibrations for some runs
718
*** few runs where HMS cal totally failed (which was dependent on initial parameters)
719
*** Spring looked worse than the rest (surprisingly), but this may be because online calibration wasn't great

727
* Timing update (Stephen)
728
** Reference times between Richard and Stephen are very similar and the GitHub is updated accordingly
729
** Richard is going to add the trigger time cuts once the fall runs are finished (by end of week)
730
** First pass of detector reference time parameter files finished
731 1 Richard Trotta
732 68 Richard Trotta
* Peter's hcana code (Richard and Stephen)
733
** Peter's code does not remove ghost bands (already known), but now Stephen is seeing a strang horizontal band for just SHMS hodoscope 2D plots
734
*** Richard has emailed Peter about the issue with no response yet (follow-up soon)
735
** 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.
736
737
* Calibrations were decided to be done once per shift
738
739
* Next meeting schedule...
740 127 Richard Trotta
** Small meetings Nov 12 and Nov 19 (at 3pm EST) so Richard and Stephen can iron out the timing and calibrations
741
** November 26 (at 3pm EST) will be a larger meeting. 
742 68 Richard Trotta
*** This is the rough deadline we made for finishing up calibrations. 
743
*** This should be sufficient for all detectors (although hodoscope and HG which may persist). The ultimate goal is for all calibrations to be finished up before Winter break!!

* SHMS Reference Time Amplitude Cuts(Stephen)
752
** Extra peaks in HG from cross-talk and "ghost-bands" due to ADC screw up
753
*** cuts applied on SHMS ADC ref time amplitude (greater than zero) done before any further event selection and histogram filling
754
** This is a temporary fix to "ghost-bands" and cross talk
755
*** Although for HG there is still a small peak. The hodoscope is fine.
756
** The time window is easier to set now.
757
** DC has been fine (since it uses TDC)
758
*** DC calibrations should be good to complete, other detectors need more fixes (i.e. the remaining "ghost-band")
759
** Hodoscope still bad but this might be because of that "ghost-band", needs to be further investigated
760
761 1 Richard Trotta
* Peter's hcana fixes for reference time (Richard)
762 67 Richard Trotta
** Peter implemented changes to hcana
763
** Two major issues...
764 1 Richard Trotta
## Amplitude goes to null and integral is low or negative which causes a rate-dependent efficiency. 
765 67 Richard Trotta
*** Peter has used the average pulse value acquired over a large sample of runs for each detector. 
766 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)
767 67 Richard Trotta
*** Peter created a routine to find the best offset by means of matching TDC and ADC
768
** Richard has been checking for bugs in the code. 
769
*** It seems to be ready to implement, Richard emailed Peter for confirmation on the implementation in our group directory
770
771 1 Richard Trotta
* Calibration of HMS detectors when the timing is agreed upon by Stephen and Richard.
772 67 Richard Trotta
** Besides hodoscope which still has an issue with the script
773 65 Richard Trotta
** Stephen and Richard are having a meeting late next week to determine time window values
774 62 Richard Trotta
*** These will be relatively final, but on the wider side if adjustments need to be made in the future

908
** resolving differences between his analysis and Richard's
909
910
* Richard
911
** 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
912
** 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)
952
** Tracking-based analysis for Runs 1415-1423, .. for now focus on HMS, typical HMS S1X rates are <
953
** Cuts applied: PID for electrons (Cer, Cal), acceptance (delta)
954
** Efficiency calculation was investigated in detail and applied using scalers from trees
955
** Results for carbon (normalized to 30uA) show large variation - need to understand
956
** *Next steps:*
957
*** Double check calculation of computer lifetime, look for differences in TRIG and PRETRIG scalers
958
*** Check stability of pre-scale (Ryan saw changes within runs)
959
*** Check if detector calibrations for runs are implemented correctly
960
*** Analyze with Ryan's cuts
961 1 Richard Trotta
962 35 Stephen Kay
* Luminosity Scans April 2018 (Ryan)
963
** Confirms Richard's earlier finding that scaler-based analysis is not reliable and that it's best to analyze event-by-event
964
** Tracking-based analysis for runs 2073-2095
965
** Cuts applied: PID for electrons (TOF, Cal, Chi2), acceptance (delta and angles), BCM4a
966
** Included most recent detector calibrations in replay of these runs
967
** Efficiencies from report file mainly, may need to update tracking efficiency implementation
968
** Found that calculations of computer deadtime requires different set of scalers for runs from January to those from April 2018
969
** Results show carbon yields consistent with unity within error (0.5% error bars), and boiling for hydrogen and deuterium
970
** *Next steps:*
971 5 Richard Trotta
*** Check tracking efficiency
972 35 Stephen Kay
973
* *Global comments on Luminosity Scans (so far)*
974 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.
975 35 Stephen Kay
** Efficiencies in report files need to be updated, e.g. CPU deadtime (Richard)
976
** Check if BCM4a is the one closest to the target - get a map of the hall (Richard, Ryan)
977
** Uncertainties on current
978

979 1 Richard Trotta
** HMS vs. SHMS

* eK+ coincidence time from SIDIS Spring 2018 run (Samip)
982
** Worked with Mark Jones on coincidence time calculation - now available in hcana (see Samip's 10 May 2018 email for more details)
983
** runs used in this analysis: 3423 with Q2=3.1 GeV2 and W=2.78 GeV
984
** Coincidence time spectrum shows peak separations >2 ns corresponding to different accelerator frequency
985
** Missing mass spectra: Kaon peak clearly visible, also see pions even after cuts
986
** Found that pions appear localized in phase space - seems to be due to end point in kinematic phase space
987 1 Richard Trotta
** *Next steps:*
988 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)
989 35 Stephen Kay
990
* Yield normalized ratios from SIDIS (Hem)
991
** Yield ratios of data to MC match well in shape, but normalization seems not quite right
992
** *Next steps:*
993 4 Richard Trotta
*** Check if efficiencies, currents, run time etc. are taken into account correctly

* Discussion luminosity scan analysis (earlier scan) - Richard
1002
** 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
1003
** Notes on efficiencies in report file:
1004
*** DT (EDTM) is not electronic deadtime. Instead use for now 50ns* trigger rate for HMS and 100ns* trigger rate for SHMS
1005
*** Cherenkov efficiency seems low (check if that is due to PID, thresholds, pi/e, etc)
1006
*** Tracking efficiency needs to be checked
1007
*** 3/4 trigger efficiency seems ok
1008
* Discussion luminosity scan analysis (later scan) - Ryan

** Fewer carbon runs than earlier scan
1010
** Shown is a tracking-based analysis using data from the ROOT trees
1011 111 Richard Trotta
** First results for carbon, LH3, and LD2, but efficiencies need to be checked
1012 35 Stephen Kay
* SIDIS analysis - Hem
1013
** Shown is a data/MC comparison for different kinematic settings. Agreement in shape is very good. Normalization has yet to be applied.
1014
** Discussion about agreement in z and apparent offset - relation of this offset with spectrometer offset
1015
* Analysis of exclusive events in SIDIS - Samip
1016
** Shown is a look at the first kaon events in exclusive limit of SIDIS data
1017
** Ongoing work on implementing coincidence time into tree
1018
* Discussion of run plan, and in particular possible low Q2/low energy
1019
** Assume that kaon low Q2=0.4 already included - have kinematics with specified beam energies, if needed
1020
** 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
1021
** Garth will put this together in a draft email
