** By setting the parameters for the interference terms to zero, the spike in data between 220-300 deg has been removed, and all ratios are within ~10. The weight iteration script is being debugged and thoroughly checked.

** The testing of global fitting parameters (offsets) for the summer 2019 data (Garth study) has been completed. 
29 630 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.
30 629 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.

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.

** 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.

** 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.
692
** 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.

742
** I've plotted the offsets vs SHMS central momentum. Plots are attached in the attached pdf file.

744
** The 10.6 GeV heep analysis is going well but the broad momentum distributions are making offsets difficult at times.
745
** 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. 
746
** 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.

** 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). 
1038
** 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.

1370
** Small meetings Nov 12 and Nov 19 (at 3pm EST) so Richard and Stephen can iron out the timing and calibrations
1371 68 Richard Trotta
** November 26 (at 3pm EST) will be a larger meeting. 
1372
*** This is the rough deadline we made for finishing up calibrations. 
1373
*** 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)
1382
** Extra peaks in HG from cross-talk and "ghost-bands" due to ADC screw up
1383
*** cuts applied on SHMS ADC ref time amplitude (greater than zero) done before any further event selection and histogram filling
1384
** This is a temporary fix to "ghost-bands" and cross talk
1385
*** Although for HG there is still a small peak. The hodoscope is fine.
1386
** The time window is easier to set now.
1387
** DC has been fine (since it uses TDC)
1388
*** DC calibrations should be good to complete, other detectors need more fixes (i.e. the remaining "ghost-band")
1389
** Hodoscope still bad but this might be because of that "ghost-band", needs to be further investigated
1390 1 Richard Trotta
1391 67 Richard Trotta
* Peter's hcana fixes for reference time (Richard)
1392
** Peter implemented changes to hcana
1393 1 Richard Trotta
** Two major issues...
1394 67 Richard Trotta
## Amplitude goes to null and integral is low or negative which causes a rate-dependent efficiency. 
1395 1 Richard Trotta
*** Peter has used the average pulse value acquired over a large sample of runs for each detector. 
1396 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)
1397
*** Peter created a routine to find the best offset by means of matching TDC and ADC
1398
** Richard has been checking for bugs in the code. 
1399
*** It seems to be ready to implement, Richard emailed Peter for confirmation on the implementation in our group directory
1400 1 Richard Trotta
1401 67 Richard Trotta
* Calibration of HMS detectors when the timing is agreed upon by Stephen and Richard.
1402 65 Richard Trotta
** Besides hodoscope which still has an issue with the script
1403 62 Richard Trotta
** Stephen and Richard are having a meeting late next week to determine time window values
1404
*** These will be relatively final, but on the wider side if adjustments need to be made in the future

* Richard
1541
** 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
1542
** 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.

1557 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
1558
** Carbon scans from January (low rates) have large deviations from unity, in particular behavior at higher currents (>40uA), e.g. cpu dead time, that is not yet understood

* Luminosity Scans January 2018 (Richard)
1582
** Tracking-based analysis for Runs 1415-1423, .. for now focus on HMS, typical HMS S1X rates are <
1583
** Cuts applied: PID for electrons (Cer, Cal), acceptance (delta)
1584
** Efficiency calculation was investigated in detail and applied using scalers from trees
1585
** Results for carbon (normalized to 30uA) show large variation - need to understand
1586
** *Next steps:*
1587
*** Double check calculation of computer lifetime, look for differences in TRIG and PRETRIG scalers
1588
*** Check stability of pre-scale (Ryan saw changes within runs)
1589
*** Check if detector calibrations for runs are implemented correctly
1590 1 Richard Trotta
*** Analyze with Ryan's cuts
1591 35 Stephen Kay
1592
* Luminosity Scans April 2018 (Ryan)
1593
** Confirms Richard's earlier finding that scaler-based analysis is not reliable and that it's best to analyze event-by-event
1594
** Tracking-based analysis for runs 2073-2095
1595
** Cuts applied: PID for electrons (TOF, Cal, Chi2), acceptance (delta and angles), BCM4a
1596
** Included most recent detector calibrations in replay of these runs
1597
** Efficiencies from report file mainly, may need to update tracking efficiency implementation
1598
** Found that calculations of computer deadtime requires different set of scalers for runs from January to those from April 2018
1599
** Results show carbon yields consistent with unity within error (0.5% error bars), and boiling for hydrogen and deuterium
1600 5 Richard Trotta
** *Next steps:*
1601 35 Stephen Kay
*** Check tracking efficiency
1602
1603 1 Richard Trotta
* *Global comments on Luminosity Scans (so far)*
1604 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.
1605
** Efficiencies in report files need to be updated, e.g. CPU deadtime (Richard)
1606
** Check if BCM4a is the one closest to the target - get a map of the hall (Richard, Ryan)
1607
** Uncertainties on current
1608 1 Richard Trotta

1609 35 Stephen Kay

* eK+ coincidence time from SIDIS Spring 2018 run (Samip)
1612
** Worked with Mark Jones on coincidence time calculation - now available in hcana (see Samip's 10 May 2018 email for more details)
1613
** runs used in this analysis: 3423 with Q2=3.1 GeV2 and W=2.78 GeV
1614
** Coincidence time spectrum shows peak separations >2 ns corresponding to different accelerator frequency
1615
** Missing mass spectra: Kaon peak clearly visible, also see pions even after cuts
1616 1 Richard Trotta
** Found that pions appear localized in phase space - seems to be due to end point in kinematic phase space
1617 2 Richard Trotta
** *Next steps:*
1618 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)
1619
1620
* Yield normalized ratios from SIDIS (Hem)
1621
** Yield ratios of data to MC match well in shape, but normalization seems not quite right
1622 4 Richard Trotta
** *Next steps:*
1623
*** Check if efficiencies, currents, run time etc. are taken into account correctly

* Discussion luminosity scan analysis (earlier scan) - Richard
1632
** 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
1633
** Notes on efficiencies in report file:
1634
*** DT (EDTM) is not electronic deadtime. Instead use for now 50ns* trigger rate for HMS and 100ns* trigger rate for SHMS
1635
*** Cherenkov efficiency seems low (check if that is due to PID, thresholds, pi/e, etc)
1636
*** Tracking efficiency needs to be checked
1637
*** 3/4 trigger efficiency seems ok
1638

1643
** Shown is a data/MC comparison for different kinematic settings. Agreement in shape is very good. Normalization has yet to be applied.
1644
** Discussion about agreement in z and apparent offset - relation of this offset with spectrometer offset
1645
* Analysis of exclusive events in SIDIS - Samip
1646
** Shown is a look at the first kaon events in exclusive limit of SIDIS data
1647
** Ongoing work on implementing coincidence time into tree
1648
* Discussion of run plan, and in particular possible low Q2/low energy
1649
** Assume that kaon low Q2=0.4 already included - have kinematics with specified beam energies, if needed
1650
** 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
1651
** Garth will put this together in a draft email

1673
** 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
1674
** 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
