** Improvements to luminosity analysis. Things are getting within a few percent. There are still some obvious issues with dependency leaking into the cuts, especially for tracking which is being investigated further.

** Uncertainties for the luminosities and heep are next up.

** 3.6 and 3.9 GeV data do NOT have the angle offsets. This has been established in the study.
56 370 Richard Trotta
** I've plotted the offsets vs SHMS central momentum. Plots are attached in the attached pdf file.
57
* Richard
58
** The 10.6 GeV heep analysis is going well but the broad momentum distributions are making offsets difficult at times.
59
** 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. 
60
** 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.

** HeeP coin for 10p6 setting is looking pretty good. I still need to make some minor adjustments.
75
** TLT for Lumi is looking much better. The yields also are looking better but cut adjustments need to be made.
76
** HeeP singles have some odd issues that need to be resolved before offset analysis can begin.

** Hodoscope calibrations are all done except 6p2.

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.

** 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). 
352
** 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.

*Analysis Updates:*
850
851

852
** resolving differences between his analysis and Richard's
853
854
* Richard
855
** 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
856
** 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)
896
** Tracking-based analysis for Runs 1415-1423, .. for now focus on HMS, typical HMS S1X rates are <
897
** Cuts applied: PID for electrons (Cer, Cal), acceptance (delta)
898
** Efficiency calculation was investigated in detail and applied using scalers from trees
899
** Results for carbon (normalized to 30uA) show large variation - need to understand
900
** *Next steps:*
901
*** Double check calculation of computer lifetime, look for differences in TRIG and PRETRIG scalers
902
*** Check stability of pre-scale (Ryan saw changes within runs)
903
*** Check if detector calibrations for runs are implemented correctly
904
*** Analyze with Ryan's cuts
905 1 Richard Trotta
906 35 Stephen Kay
* Luminosity Scans April 2018 (Ryan)
907
** Confirms Richard's earlier finding that scaler-based analysis is not reliable and that it's best to analyze event-by-event
908
** Tracking-based analysis for runs 2073-2095
909
** Cuts applied: PID for electrons (TOF, Cal, Chi2), acceptance (delta and angles), BCM4a
910
** Included most recent detector calibrations in replay of these runs
911
** Efficiencies from report file mainly, may need to update tracking efficiency implementation
912
** Found that calculations of computer deadtime requires different set of scalers for runs from January to those from April 2018
913
** Results show carbon yields consistent with unity within error (0.5% error bars), and boiling for hydrogen and deuterium
914
** *Next steps:*
915 5 Richard Trotta
*** Check tracking efficiency
916 35 Stephen Kay
917
* *Global comments on Luminosity Scans (so far)*
918 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.
919 35 Stephen Kay
** Efficiencies in report files need to be updated, e.g. CPU deadtime (Richard)
920
** Check if BCM4a is the one closest to the target - get a map of the hall (Richard, Ryan)
921
** Uncertainties on current
922
** Detector calibrations
923 1 Richard Trotta
** HMS vs. SHMS
924 35 Stephen Kay
925
* eK+ coincidence time from SIDIS Spring 2018 run (Samip)
926
** Worked with Mark Jones on coincidence time calculation - now available in hcana (see Samip's 10 May 2018 email for more details)
927
** runs used in this analysis: 3423 with Q2=3.1 GeV2 and W=2.78 GeV
928
** Coincidence time spectrum shows peak separations >2 ns corresponding to different accelerator frequency
929
** Missing mass spectra: Kaon peak clearly visible, also see pions even after cuts
930
** Found that pions appear localized in phase space - seems to be due to end point in kinematic phase space
931 1 Richard Trotta
** *Next steps:*
932 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)
933 35 Stephen Kay
934
* Yield normalized ratios from SIDIS (Hem)
935
** Yield ratios of data to MC match well in shape, but normalization seems not quite right
936
** *Next steps:*
937 4 Richard Trotta
*** Check if efficiencies, currents, run time etc. are taken into account correctly

945 35 Stephen Kay
* Discussion luminosity scan analysis (earlier scan) - Richard
946
** 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
947
** Notes on efficiencies in report file:
948
*** DT (EDTM) is not electronic deadtime. Instead use for now 50ns* trigger rate for HMS and 100ns* trigger rate for SHMS
949
*** Cherenkov efficiency seems low (check if that is due to PID, thresholds, pi/e, etc)
950
*** Tracking efficiency needs to be checked
951
*** 3/4 trigger efficiency seems ok
952
* Discussion luminosity scan analysis (later scan) - Ryan
953
** Fewer carbon runs than earlier scan
954
** Shown is a tracking-based analysis using data from the ROOT trees
955 111 Richard Trotta
** First results for carbon, LH3, and LD2, but efficiencies need to be checked
956 35 Stephen Kay
* SIDIS analysis - Hem
957
** Shown is a data/MC comparison for different kinematic settings. Agreement in shape is very good. Normalization has yet to be applied.
958
** Discussion about agreement in z and apparent offset - relation of this offset with spectrometer offset
959
* Analysis of exclusive events in SIDIS - Samip
960
** Shown is a look at the first kaon events in exclusive limit of SIDIS data
961
** Ongoing work on implementing coincidence time into tree
962
* Discussion of run plan, and in particular possible low Q2/low energy
963
** Assume that kaon low Q2=0.4 already included - have kinematics with specified beam energies, if needed
964
** 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
965
** 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
986
* Discussion of Richard's slides on run plan kinematics and preparations -
987
** 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
988
** 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
