** t-range: Adjusted from 0.15-0.6 to 0.16-0.6.
66
** Binning Scheme: Changed to 5 bins in t and 10 bins in phi. Increased the number of events per bin.
67
*** Outcome: Significant reduction in pion leakage for the lowest t-bin.
68
** Upper t-range: Need to reduced from 0.6 to 0.5 to address high-background issues in the highest t-bin.

** HeeP ratios are consistent with my previous results (slight changes from improvements to HMS cherenkov/calorimeter efficiency). There are some inconsistencies between Nacer and me, specifically with the SHMS Hodo efficiencies. My replays were from Dec. 2023, so I want to rerun all replays to double-check consistency between my results.

** Q=4.4/W=2.74 results were included in the KaonLT global comparison from last week. Q2=3.0/W=2.32 were running and slides will be posted when these are finished up to get the KaonLT global comparison for all Q2 (minus Q2=0.5).

** The effect of varying individual acceptance cuts (delta, xptar, yptar) by ±10% at a time on the separated cross-sections has been analyzed.
309
** The net effect on the separated cross-sections was determined by summing the uncertainties in quadrature for all six cuts (delta, xptar, yptar, each has two cuts).
310
** For SHMS
311
*** SigL: Varies between 0.1% and 0.8%

** The resolution of MC looked worse than data after t-bining. This will be improved with a lower multiplication factor.

** SIMC Weight
709
*** 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. 
710
** SIMC MM
711
*** 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.
712
** MM PID Analysis
713
*** Played around with MM cuts to see PID of leak through/higher K+ channels.
714
*** Increasing aerogel cut from aero > 3.0 to > 4.5 should resolve some of the issues, but more probably needs to be done.
715
** MM cut: Yield Comparison
716
*** 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.

736
** Issues with dummy runs
737
*** The dtype error for some dummy runs was caused by empty trees when applying the CT cuts.
738
*** 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.
739
** Weird t-distribution
740
*** Multiple peaks seen in the t-distribution were caused by various particle leakthrough.
741
*** 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.
742
** Fixed binning issue
743
*** Issue with the binning script was causing many average kin per bin values to be zero. 
744
*** The scripts were completely rewritten and things look very nice now.
745
** Separated Xsects Script
746
*** Finished debugging the script that separates the cross section. 
747
*** The binning issue was hiding other FORTRAN related issues, in particular, with the input files that are generated.
748
** SIMC MM
749
*** Very broad and long tail on kaon MM generated by SIMC. Still under investigation.
750
** SIMC High Q2
751
*** There were negative MM and other variables being generated by SIMC for high Q2 settings.
752
*** 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.

** 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. 
1408
** 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.

** 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.
1452
** 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.

** 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.
1552
** 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 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.

2126
*** Tighter cuts and cuts on timing, beta, etc. will be needed for cleaner electron cuts
2127

*** Richard will pick up looking at the HGCer calibrations from Vijay's scripts. 
2185
*** Richard will also be looking at the SHMS calorimeter and with the suggestion of getting some negatively polarized SHMS runs from Hem.
2186
** The HMS Cherenkov is finished with the conclusion that the calibrations from the online runs are good
2187
** We can begin looking forward towards efficiencies. 
2188
*** Garth suggested that looking at PID may be an advantageous first steps. Precise definitions of these PIDs will need to be logged.

** This is a temporary fix to "ghost-bands" and cross talk
2245
*** Although for HG there is still a small peak. The hodoscope is fine.
2246
** The time window is easier to set now.
2247
** DC has been fine (since it uses TDC)
2248
*** DC calibrations should be good to complete, other detectors need more fixes (i.e. the remaining "ghost-band")

* Peter's hcana fixes for reference time (Richard)
2252
** Peter implemented changes to hcana
2253 1 Richard Trotta
** Two major issues...
2254 67 Richard Trotta
## Amplitude goes to null and integral is low or negative which causes a rate-dependent efficiency. 
2255 1 Richard Trotta
*** Peter has used the average pulse value acquired over a large sample of runs for each detector. 
2256 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)
2257
*** Peter created a routine to find the best offset by means of matching TDC and ADC
2258
** Richard has been checking for bugs in the code. 
2259
*** It seems to be ready to implement, Richard emailed Peter for confirmation on the implementation in our group directory

** Stephen and Richard are having a meeting late next week to determine time window values

* Richard
2401
** 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
2402
** 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)
2442
** Tracking-based analysis for Runs 1415-1423, .. for now focus on HMS, typical HMS S1X rates are <
2443
** Cuts applied: PID for electrons (Cer, Cal), acceptance (delta)
2444
** Efficiency calculation was investigated in detail and applied using scalers from trees
2445
** Results for carbon (normalized to 30uA) show large variation - need to understand
2446
** *Next steps:*
2447
*** Double check calculation of computer lifetime, look for differences in TRIG and PRETRIG scalers
2448
*** Check stability of pre-scale (Ryan saw changes within runs)
2449
*** Check if detector calibrations for runs are implemented correctly
2450 1 Richard Trotta
*** Analyze with Ryan's cuts
2451 35 Stephen Kay
2452
* Luminosity Scans April 2018 (Ryan)
2453
** Confirms Richard's earlier finding that scaler-based analysis is not reliable and that it's best to analyze event-by-event
2454
** Tracking-based analysis for runs 2073-2095
2455
** Cuts applied: PID for electrons (TOF, Cal, Chi2), acceptance (delta and angles), BCM4a
2456
** Included most recent detector calibrations in replay of these runs
2457
** Efficiencies from report file mainly, may need to update tracking efficiency implementation
2458
** Found that calculations of computer deadtime requires different set of scalers for runs from January to those from April 2018
2459
** Results show carbon yields consistent with unity within error (0.5% error bars), and boiling for hydrogen and deuterium
2460 5 Richard Trotta
** *Next steps:*
2461 35 Stephen Kay
*** Check tracking efficiency
2462
2463 1 Richard Trotta
* *Global comments on Luminosity Scans (so far)*
2464 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.
2465
** Efficiencies in report files need to be updated, e.g. CPU deadtime (Richard)
2466
** 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)
2472
** Worked with Mark Jones on coincidence time calculation - now available in hcana (see Samip's 10 May 2018 email for more details)
2473
** runs used in this analysis: 3423 with Q2=3.1 GeV2 and W=2.78 GeV
2474
** Coincidence time spectrum shows peak separations >2 ns corresponding to different accelerator frequency
2475
** Missing mass spectra: Kaon peak clearly visible, also see pions even after cuts
2476 1 Richard Trotta
** Found that pions appear localized in phase space - seems to be due to end point in kinematic phase space
2477 2 Richard Trotta
** *Next steps:*
2478 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)
2479
2480
* Yield normalized ratios from SIDIS (Hem)
2481
** Yield ratios of data to MC match well in shape, but normalization seems not quite right
2482 4 Richard Trotta
** *Next steps:*
2483
*** Check if efficiencies, currents, run time etc. are taken into account correctly

* Discussion luminosity scan analysis (earlier scan) - Richard
2492
** 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
2493
** Notes on efficiencies in report file:
2494
*** DT (EDTM) is not electronic deadtime. Instead use for now 50ns* trigger rate for HMS and 100ns* trigger rate for SHMS
2495
*** Cherenkov efficiency seems low (check if that is due to PID, thresholds, pi/e, etc)
2496
*** Tracking efficiency needs to be checked
2497
*** 3/4 trigger efficiency seems ok
2498
* Discussion luminosity scan analysis (later scan) - Ryan
2499

* SIDIS analysis - Hem
2503
** Shown is a data/MC comparison for different kinematic settings. Agreement in shape is very good. Normalization has yet to be applied.
2504
** Discussion about agreement in z and apparent offset - relation of this offset with spectrometer offset
2505
* Analysis of exclusive events in SIDIS - Samip
2506
** Shown is a look at the first kaon events in exclusive limit of SIDIS data
2507
** Ongoing work on implementing coincidence time into tree
2508
* Discussion of run plan, and in particular possible low Q2/low energy
2509
** Assume that kaon low Q2=0.4 already included - have kinematics with specified beam energies, if needed
2510
** 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
2511
** 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
2532
* Discussion of Richard's slides on run plan kinematics and preparations -
2533
** 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
2534
** 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
2535
** for each setting will need 1-2 shifts for calibrations - need to negotiate with other experiments in run group
