** It looks like the efficiency is less from the production data (Q2 = 0.38 GeV2, High e).
159
** I'll take a look at the heep coin data in this run period of the experiment and get the efficiency. 
160 547 Ali Usman
** Hopefully that's number, the efficiency from heep coin data, will be reliable to correct the inefficiency of the detector and correct the data run by run.

** Carlos has been working on the rate dependence issue for the luminosity scans that Casey and I have been seeing. He came to a similar conclusion as me that there will need to be a correction factor that we all agree on that will need to be applied. We are meeting on Monday to discuss things further. "See his slides on the docDB":https://hallcweb.jlab.org/doc-private/ShowDocument?docid=1206

** 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.

** 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.
462
** 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.
542
*** It should be noted, there are huge discrepancies between BCM4A and BCM1 in some cases (like 20+ uA).
543
** 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.
562
** 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.

*** Tighter cuts and cuts on timing, beta, etc. will be needed for cleaner electron cuts
1137

1263 1 Richard Trotta
** Two major issues...
1264 67 Richard Trotta
## Amplitude goes to null and integral is low or negative which causes a rate-dependent efficiency. 
1265 1 Richard Trotta
*** Peter has used the average pulse value acquired over a large sample of runs for each detector. 
1266 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)
1267
*** Peter created a routine to find the best offset by means of matching TDC and ADC
1268
** Richard has been checking for bugs in the code. 
1269
*** It seems to be ready to implement, Richard emailed Peter for confirmation on the implementation in our group directory

1410
* Richard
1411
** 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
1412
** 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.

1427 35 Stephen Kay
** Carbon scan from April seems consistent with no boiling, LH3 and LD2 show deviation from unity, should check effect of EDTM events on efficiencies

* Luminosity Scans January 2018 (Richard)
1452
** Tracking-based analysis for Runs 1415-1423, .. for now focus on HMS, typical HMS S1X rates are <
1453
** Cuts applied: PID for electrons (Cer, Cal), acceptance (delta)
1454
** Efficiency calculation was investigated in detail and applied using scalers from trees
1455
** Results for carbon (normalized to 30uA) show large variation - need to understand
1456
** *Next steps:*
1457
*** Double check calculation of computer lifetime, look for differences in TRIG and PRETRIG scalers
1458
*** Check stability of pre-scale (Ryan saw changes within runs)
1459
*** Check if detector calibrations for runs are implemented correctly
1460 1 Richard Trotta
*** Analyze with Ryan's cuts
1461 35 Stephen Kay
1462
* Luminosity Scans April 2018 (Ryan)
1463
** Confirms Richard's earlier finding that scaler-based analysis is not reliable and that it's best to analyze event-by-event
1464
** Tracking-based analysis for runs 2073-2095
1465
** Cuts applied: PID for electrons (TOF, Cal, Chi2), acceptance (delta and angles), BCM4a
1466
** Included most recent detector calibrations in replay of these runs
1467
** Efficiencies from report file mainly, may need to update tracking efficiency implementation
1468
** Found that calculations of computer deadtime requires different set of scalers for runs from January to those from April 2018
1469
** Results show carbon yields consistent with unity within error (0.5% error bars), and boiling for hydrogen and deuterium
1470 5 Richard Trotta
** *Next steps:*
1471 35 Stephen Kay
*** Check tracking efficiency
1472
1473 1 Richard Trotta
* *Global comments on Luminosity Scans (so far)*
1474 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.
1475
** Efficiencies in report files need to be updated, e.g. CPU deadtime (Richard)
1476
** Check if BCM4a is the one closest to the target - get a map of the hall (Richard, Ryan)
1477

* eK+ coincidence time from SIDIS Spring 2018 run (Samip)
1482
** Worked with Mark Jones on coincidence time calculation - now available in hcana (see Samip's 10 May 2018 email for more details)
1483
** runs used in this analysis: 3423 with Q2=3.1 GeV2 and W=2.78 GeV
1484
** Coincidence time spectrum shows peak separations >2 ns corresponding to different accelerator frequency
1485
** Missing mass spectra: Kaon peak clearly visible, also see pions even after cuts
1486 1 Richard Trotta
** Found that pions appear localized in phase space - seems to be due to end point in kinematic phase space
1487 2 Richard Trotta
** *Next steps:*
1488 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)
1489
1490
* Yield normalized ratios from SIDIS (Hem)
1491
** Yield ratios of data to MC match well in shape, but normalization seems not quite right
1492 4 Richard Trotta
** *Next steps:*
1493
*** Check if efficiencies, currents, run time etc. are taken into account correctly

* Discussion luminosity scan analysis (earlier scan) - Richard
1502
** 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
1503
** Notes on efficiencies in report file:
1504
*** DT (EDTM) is not electronic deadtime. Instead use for now 50ns* trigger rate for HMS and 100ns* trigger rate for SHMS
1505
*** Cherenkov efficiency seems low (check if that is due to PID, thresholds, pi/e, etc)
1506
*** Tracking efficiency needs to be checked
1507
*** 3/4 trigger efficiency seems ok
1508
* Discussion luminosity scan analysis (later scan) - Ryan
1509
** Fewer carbon runs than earlier scan
1510 111 Richard Trotta

1511 35 Stephen Kay
** First results for carbon, LH3, and LD2, but efficiencies need to be checked
1512
* SIDIS analysis - Hem
1513
** Shown is a data/MC comparison for different kinematic settings. Agreement in shape is very good. Normalization has yet to be applied.
1514
** Discussion about agreement in z and apparent offset - relation of this offset with spectrometer offset
1515
* Analysis of exclusive events in SIDIS - Samip
1516
** Shown is a look at the first kaon events in exclusive limit of SIDIS data
1517
** Ongoing work on implementing coincidence time into tree
1518
* Discussion of run plan, and in particular possible low Q2/low energy
1519
** Assume that kaon low Q2=0.4 already included - have kinematics with specified beam energies, if needed
1520
** 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
1521
** 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
1542
* Discussion of Richard's slides on run plan kinematics and preparations -
1543
** 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
1544
** 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
1545
** for each setting will need 1-2 shifts for calibrations - need to negotiate with other experiments in run group
