** 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.
95
** OOP offsets are also looked at, but there is an obvious issue with their implementation that needs to be resolved.

123
** The testing of global fitting parameters (offsets) for the summer 2019 data (Garth study) has been completed. 
124 630 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.
125 629 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.

** 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.

734
** 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.

** 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.
767

** 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.
787
** 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.
840
** 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. 
841
** 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). 
1133
** 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.

** PID efficiency script is coming together
1361
*** Tighter cuts and cuts on timing, beta, etc. will be needed for cleaner electron cuts
1362
*** Hcal cut should be changed to cut around the mean normalized value instead of cutting above or below it only. This will assure electrons aren't lost.

** 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.
1419
*** Richard will pick up looking at the HGCer calibrations from Vijay's scripts. 
1420
*** Richard will also be looking at the SHMS calorimeter and with the suggestion of getting some negatively polarized SHMS runs from Hem.
1421
** The HMS Cherenkov is finished with the conclusion that the calibrations from the online runs are good
1422
** We can begin looking forward towards efficiencies. 
1423
*** Garth suggested that looking at PID may be an advantageous first steps. Precise definitions of these PIDs will need to be logged.
1424
*** Clear notes on efficiencies steps will be needed. They will need to be redefined multiple times in multiple ways.

* Peter's hcana code (Richard and Stephen)
1458

1459
*** Richard has emailed Peter about the issue with no response yet (follow-up soon)
1460
** 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)
1477
** Extra peaks in HG from cross-talk and "ghost-bands" due to ADC screw up
1478
*** cuts applied on SHMS ADC ref time amplitude (greater than zero) done before any further event selection and histogram filling
1479
** This is a temporary fix to "ghost-bands" and cross talk
1480
*** Although for HG there is still a small peak. The hodoscope is fine.
1481
** The time window is easier to set now.
1482
** DC has been fine (since it uses TDC)
1483
*** DC calibrations should be good to complete, other detectors need more fixes (i.e. the remaining "ghost-band")
1484
** 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)
1487
** Peter implemented changes to hcana
1488 1 Richard Trotta
** Two major issues...
1489 67 Richard Trotta
## Amplitude goes to null and integral is low or negative which causes a rate-dependent efficiency. 
1490 1 Richard Trotta
*** Peter has used the average pulse value acquired over a large sample of runs for each detector. 
1491 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)
1492
*** Peter created a routine to find the best offset by means of matching TDC and ADC
1493
** Richard has been checking for bugs in the code. 
1494
*** It seems to be ready to implement, Richard emailed Peter for confirmation on the implementation in our group directory
1495 1 Richard Trotta
1496 67 Richard Trotta
* Calibration of HMS detectors when the timing is agreed upon by Stephen and Richard.
1497 65 Richard Trotta
** Besides hodoscope which still has an issue with the script
1498 62 Richard Trotta
** Stephen and Richard are having a meeting late next week to determine time window values
1499
*** These will be relatively final, but on the wider side if adjustments need to be made in the future

** 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
1637
** 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.

1695 5 Richard Trotta
** *Next steps:*
1696 35 Stephen Kay
*** Check tracking efficiency
1697
1698 1 Richard Trotta
* *Global comments on Luminosity Scans (so far)*
1699 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.
1700
** Efficiencies in report files need to be updated, e.g. CPU deadtime (Richard)
1701
** Check if BCM4a is the one closest to the target - get a map of the hall (Richard, Ryan)
1702
** Uncertainties on current
1703 1 Richard Trotta
** Detector calibrations
1704 35 Stephen Kay
** HMS vs. SHMS

* eK+ coincidence time from SIDIS Spring 2018 run (Samip)
1707
** Worked with Mark Jones on coincidence time calculation - now available in hcana (see Samip's 10 May 2018 email for more details)
1708
** runs used in this analysis: 3423 with Q2=3.1 GeV2 and W=2.78 GeV
1709
** Coincidence time spectrum shows peak separations >2 ns corresponding to different accelerator frequency
1710
** Missing mass spectra: Kaon peak clearly visible, also see pions even after cuts
1711 1 Richard Trotta
** Found that pions appear localized in phase space - seems to be due to end point in kinematic phase space
1712 2 Richard Trotta
** *Next steps:*
1713 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)
1714
1715
* Yield normalized ratios from SIDIS (Hem)
1716
** Yield ratios of data to MC match well in shape, but normalization seems not quite right
1717 4 Richard Trotta
** *Next steps:*
1718
*** Check if efficiencies, currents, run time etc. are taken into account correctly

1726
* Discussion luminosity scan analysis (earlier scan) - Richard
1727
** 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
1728
** Notes on efficiencies in report file:
1729
*** DT (EDTM) is not electronic deadtime. Instead use for now 50ns* trigger rate for HMS and 100ns* trigger rate for SHMS
1730
*** Cherenkov efficiency seems low (check if that is due to PID, thresholds, pi/e, etc)
1731
*** Tracking efficiency needs to be checked
1732
*** 3/4 trigger efficiency seems ok
1733
* Discussion luminosity scan analysis (later scan) - Ryan
1734
** Fewer carbon runs than earlier scan
1735 111 Richard Trotta
** Shown is a tracking-based analysis using data from the ROOT trees
1736 35 Stephen Kay
** First results for carbon, LH3, and LD2, but efficiencies need to be checked
1737
* SIDIS analysis - Hem
1738
** Shown is a data/MC comparison for different kinematic settings. Agreement in shape is very good. Normalization has yet to be applied.
1739
** Discussion about agreement in z and apparent offset - relation of this offset with spectrometer offset
1740
* Analysis of exclusive events in SIDIS - Samip
1741
** Shown is a look at the first kaon events in exclusive limit of SIDIS data
1742
** Ongoing work on implementing coincidence time into tree
1743
* Discussion of run plan, and in particular possible low Q2/low energy
1744
** Assume that kaon low Q2=0.4 already included - have kinematics with specified beam energies, if needed
1745
** 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
1746
** Garth will put this together in a draft email

1764 35 Stephen Kay
1765
*  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.
1766
* Brief description of Samip's work - working on coincidence timing decoding with JLab staff and re-optimization of kinematics
1767
* Discussion of Richard's slides on run plan kinematics and preparations -
1768
** 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
1769
** 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
1770
** for each setting will need 1-2 shifts for calibrations - need to negotiate with other experiments in run group
1771
** kinematics plots W-Q2 show that still need to do some optimization
1772
** run sheets: include raster size, update coincidence count labeling, and carbon target labeling
1773 26 Richard Trotta
* Discussion of next meeting. Garth at JLab 8-16 March - might have meeting during that time.
1774 35 Stephen Kay
