** CoinTime / Beta Leakage Study is now finished. Mark's suggestion to change ptof_tolerance variable from 100 to 2 has fixed the bad beta events. The efficiency for 10.6 and 6.2 / 8.2 GeV Heep dta is almost identical. No need to correct for bad beta / CoinTime events.

** A variety of heep offsets were applied, provided by Garth's global results. It is shown that adapting the 5 beam energy global offsets with varying the SHMS momentum offset allows for the best emiss peak positions.
70
** OOP offsets are also looked at, but there is an obvious issue with their implementation that needs to be resolved.

** The testing of global fitting parameters (offsets) for the summer 2019 data (Garth study) has been completed. 
99 630 Vijay Kumar
** It has been determined that employing a single set of offsets for all energies within the summer 2019 dataset does not adequately address all variables.
100 629 Vijay Kumar
** Nonetheless, the W variable exhibits a strong agreement with the SIMC for energies of 2.7 and 4.5 GeV. However, at 3.6 GeV, a slight over-correction is observed.

** 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. I tried rerunning them, but the issue has persisted. My initial guess is that it may be an issue with the TDC cuts, since the coin time distributions were looking off previously.

** 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%.
709
** 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.
710
** 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.
742
*** It should be noted, there are huge discrepancies between BCM4A and BCM1 in some cases (like 20+ uA).
743
** Ran into some issues with the cross-section code. I am in debug mode trying to find the cause.

** 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.
762
** 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.
815
** 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. 
816
** 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 currents were adjusted from 1-10 uA with little effect on the EDMTLT but proper changes to the CPULT. 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. There was also a small error in the code found where T.coin.pEDTM.tdcTimeRaw was incorrectly written as T.coin.pEDTM.tdcTime.

** 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). 
1108
** 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.

** Fixed one error issue with SHMS calorimeter calibration code (discussed Dec 10th meeting), but still have one error
1358
** PID efficiency script plots are complete, but still some questions he needs to work out before a final version
1359
*** Eventually need to include tracking into PID efficiencies
1360
** Pete brought up the question for a number of multi-hits we are getting
1361
*** (Dead Time)+(Trigger efficiency)-EDTM

* Garth and Stephen were in the most recent SIDIS meeting
1370
** Wit had lots of hcana changes but they seem to be critical to our work 
1371 1 Richard Trotta
*** Changes such as new detector classes
1372
** Hopefully Wit will present these in the next commissioning meeting
1373 77 Richard Trotta
1374 74 Richard Trotta
* Stephen improved wiggles but still prevalent
1375
1376
* Richard finished HGCer calibrations, he concluded that the online parameters are sufficient
1377
** He also has been looking at SHMS calorimeter calibrations but has had issues running the scripts. Most likely a pathing issue.
1378
** The "tasks":https://redmine.jlab.org/projects/kltexp/wiki/Analysis_Tasks page has been updated with a section for efficiencies. 
1379
*** A PID efficiency script is currently being developed and hopefully should have some plots for our next meeting.

** 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.
1394
*** Richard will pick up looking at the HGCer calibrations from Vijay's scripts. 
1395
*** Richard will also be looking at the SHMS calorimeter and with the suggestion of getting some negatively polarized SHMS runs from Hem.
1396
** The HMS Cherenkov is finished with the conclusion that the calibrations from the online runs are good
1397
** We can begin looking forward towards efficiencies. 
1398
*** Garth suggested that looking at PID may be an advantageous first steps. Precise definitions of these PIDs will need to be logged.
1399
*** Clear notes on efficiencies steps will be needed. They will need to be redefined multiple times in multiple ways.

* Hem
1402 70 Richard Trotta
** Has been looking at the calorimeter as well. 
1403
** He has seen the second band in the spectra for some runs, we suggested further looks into HMS hodoscope and subsequently reference times. A recalibration will need to be performed.

* Timing update (Stephen)
1428
** Reference times between Richard and Stephen are very similar and the GitHub is updated accordingly
1429
** Richard is going to add the trigger time cuts once the fall runs are finished (by end of week)
1430 1 Richard Trotta

* Peter's hcana code (Richard and Stephen)
1433

1434
*** Richard has emailed Peter about the issue with no response yet (follow-up soon)
1435
** 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)
1452
** Extra peaks in HG from cross-talk and "ghost-bands" due to ADC screw up
1453
*** cuts applied on SHMS ADC ref time amplitude (greater than zero) done before any further event selection and histogram filling
1454
** This is a temporary fix to "ghost-bands" and cross talk
1455
*** Although for HG there is still a small peak. The hodoscope is fine.
1456
** The time window is easier to set now.
1457
** DC has been fine (since it uses TDC)
1458
*** DC calibrations should be good to complete, other detectors need more fixes (i.e. the remaining "ghost-band")
1459
** 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)
1462
** Peter implemented changes to hcana
1463 1 Richard Trotta
** Two major issues...
1464 67 Richard Trotta
## Amplitude goes to null and integral is low or negative which causes a rate-dependent efficiency. 
1465 1 Richard Trotta
*** Peter has used the average pulse value acquired over a large sample of runs for each detector. 
1466 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)
1467
*** Peter created a routine to find the best offset by means of matching TDC and ADC
1468
** Richard has been checking for bugs in the code. 
1469
*** It seems to be ready to implement, Richard emailed Peter for confirmation on the implementation in our group directory
1470 1 Richard Trotta
1471 67 Richard Trotta
* Calibration of HMS detectors when the timing is agreed upon by Stephen and Richard.
1472 65 Richard Trotta
** Besides hodoscope which still has an issue with the script
1473 62 Richard Trotta
** Stephen and Richard are having a meeting late next week to determine time window values
1474
*** These will be relatively final, but on the wider side if adjustments need to be made in the future

1611
** 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
1612
** 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)
1652
** Tracking-based analysis for Runs 1415-1423, .. for now focus on HMS, typical HMS S1X rates are <
1653
** Cuts applied: PID for electrons (Cer, Cal), acceptance (delta)
1654
** Efficiency calculation was investigated in detail and applied using scalers from trees
1655
** Results for carbon (normalized to 30uA) show large variation - need to understand
1656
** *Next steps:*
1657
*** Double check calculation of computer lifetime, look for differences in TRIG and PRETRIG scalers
1658
*** Check stability of pre-scale (Ryan saw changes within runs)
1659
*** Check if detector calibrations for runs are implemented correctly
1660 1 Richard Trotta
*** Analyze with Ryan's cuts

* Luminosity Scans April 2018 (Ryan)
1663
** Confirms Richard's earlier finding that scaler-based analysis is not reliable and that it's best to analyze event-by-event
1664
** Tracking-based analysis for runs 2073-2095
1665
** Cuts applied: PID for electrons (TOF, Cal, Chi2), acceptance (delta and angles), BCM4a
1666
** Included most recent detector calibrations in replay of these runs
1667
** Efficiencies from report file mainly, may need to update tracking efficiency implementation
1668
** Found that calculations of computer deadtime requires different set of scalers for runs from January to those from April 2018
1669
** Results show carbon yields consistent with unity within error (0.5% error bars), and boiling for hydrogen and deuterium

* *Global comments on Luminosity Scans (so far)*
1674 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.
1675
** Efficiencies in report files need to be updated, e.g. CPU deadtime (Richard)
1676
** 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)
1682
** Worked with Mark Jones on coincidence time calculation - now available in hcana (see Samip's 10 May 2018 email for more details)
1683
** runs used in this analysis: 3423 with Q2=3.1 GeV2 and W=2.78 GeV
1684
** Coincidence time spectrum shows peak separations >2 ns corresponding to different accelerator frequency
1685
** Missing mass spectra: Kaon peak clearly visible, also see pions even after cuts
1686 1 Richard Trotta
** Found that pions appear localized in phase space - seems to be due to end point in kinematic phase space
1687 2 Richard Trotta
** *Next steps:*
1688 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)
1689
1690
* Yield normalized ratios from SIDIS (Hem)
1691
** Yield ratios of data to MC match well in shape, but normalization seems not quite right
1692 4 Richard Trotta
** *Next steps:*
1693
*** Check if efficiencies, currents, run time etc. are taken into account correctly

1701
* Discussion luminosity scan analysis (earlier scan) - Richard
1702
** 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
1703
** Notes on efficiencies in report file:
1704
*** DT (EDTM) is not electronic deadtime. Instead use for now 50ns* trigger rate for HMS and 100ns* trigger rate for SHMS
1705
*** Cherenkov efficiency seems low (check if that is due to PID, thresholds, pi/e, etc)
1706
*** Tracking efficiency needs to be checked
1707
*** 3/4 trigger efficiency seems ok
1708
* Discussion luminosity scan analysis (later scan) - Ryan
1709
** Fewer carbon runs than earlier scan
1710 111 Richard Trotta
** Shown is a tracking-based analysis using data from the ROOT trees
1711 35 Stephen Kay
** First results for carbon, LH3, and LD2, but efficiencies need to be checked
1712
* SIDIS analysis - Hem
1713
** Shown is a data/MC comparison for different kinematic settings. Agreement in shape is very good. Normalization has yet to be applied.
1714
** Discussion about agreement in z and apparent offset - relation of this offset with spectrometer offset
1715
* Analysis of exclusive events in SIDIS - Samip
1716
** Shown is a look at the first kaon events in exclusive limit of SIDIS data
1717
** Ongoing work on implementing coincidence time into tree
1718
* Discussion of run plan, and in particular possible low Q2/low energy
1719
** Assume that kaon low Q2=0.4 already included - have kinematics with specified beam energies, if needed
1720
** 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
1721
** Garth will put this together in a draft email

1739 35 Stephen Kay
1740
*  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.
1741
* Brief description of Samip's work - working on coincidence timing decoding with JLab staff and re-optimization of kinematics
1742
* Discussion of Richard's slides on run plan kinematics and preparations -
1743
** 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
1744
** 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
1745
** for each setting will need 1-2 shifts for calibrations - need to negotiate with other experiments in run group
1746
** kinematics plots W-Q2 show that still need to do some optimization
1747
** run sheets: include raster size, update coincidence count labeling, and carbon target labeling
1748 26 Richard Trotta
* Discussion of next meeting. Garth at JLab 8-16 March - might have meeting during that time.
1749 35 Stephen Kay
1750
* *Action Items:*
1751
** Post slides/notes from this meeting and procedure to set up hcana in Redmine (Tanja)
1752
** Update run sheet and kinematic optimization for W/Q2 (Garth)
1753
** Circulate elastic calculations for kinematic settings (Samip)
1754
** Continue investigation of elastic data and run plan kinematics (Andres/Richard)
1755
** Test software installation instructions (Pete)
1756 32 Stephen Kay
** Draft email to JLab management about need for small angle beam pipe - need to have HMS minimum angle of less than 13 degrees for kaon L/T separations (Tanja)
