** SHMS xptar had an odd distribution. Upon further inspection, the RF cut was the cause. There is a correlation between xptar and the RF which must have a path length correction. For KaonLT data (>Q2=0.5), the RF will no longer be used.

** Fixed issue with shrinking xsect on each iteration. The issue was a mistake in absolute error being mistaken for relative error when calculating xsect error.\
72
** Pion subtraction implemented with not much change in xsect beyond lowest t-bins. Smaller t-bins see a 50% reduction with MM cut

** Model cross-sections were compared for most of the Q2s. There were several iterations which included a +0.2 term to the t-dependence of sigL. sigT now used the model from Tanja's "global analysis":https://journals.aps.org/prc/pdf/10.1103/PhysRevC.85.018202 which is coming along. Pion subtraction still needs to be incorporated and things should improve further from there.

** Properly Calculated Statistical Uncertainties
128
*** Ali and I went through and properly implemented statistical uncertainties (double-checked with Garth on Monday). This included updating HMS cerenkov and calorimeter efficiencies that needed to use a "golden singles run" to avoid contamination. A bug in the ratio per bin was fixed so that proper average ratio per bins were found.
129
** SIMC Aerogel/HGCer geometric cuts were implemented.
130
** Particle Subtraction Script was updated. Just need pion samples from Ali.
131
** Beginning Unsep-xsect Systematic Studies
132
** Continued issues with generating new parameterization
133
*** Unsep xsect fits are starting to look good, but the script to generate improved parameterization generates insane fits. Likely a change to the model is needed. In particular, sigT will need adjustments.

** Update on the SIMC resolution study for Kaon-LT 10.6 GeV data.
142
** SIMC SHMS DC resolution was tunned to have better agreement b/w data nnd MC. A large resolution multiplication factor of 9 is used. This will hopefully decrease with improvement in data resolution.
143
** SIMC HMS DC resolution (suggested by Dave G.) doesn't make a huge difference.
144 710 Ali Usman
** The resolution of MC looked worse than data after t-bining. This will be improved with a lower multiplication factor.

** SIMC Weight
155
*** 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. 
156
** SIMC MM
157
*** 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.
158
** MM PID Analysis
159
*** Played around with MM cuts to see PID of leak through/higher K+ channels.
160
*** Increasing aerogel cut from aero > 3.0 to > 4.5 should resolve some of the issues, but more probably needs to be done.
161
** MM cut: Yield Comparison
162
*** 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.

182
** Issues with dummy runs
183
*** The dtype error for some dummy runs was caused by empty trees when applying the CT cuts.
184
*** 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.
185
** Weird t-distribution
186
*** Multiple peaks seen in the t-distribution were caused by various particle leakthrough.
187
*** 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.
188
** Fixed binning issue
189
*** Issue with the binning script was causing many average kin per bin values to be zero. 
190
*** The scripts were completely rewritten and things look very nice now.
191
** Separated Xsects Script
192
*** Finished debugging the script that separates the cross section. 
193
*** The binning issue was hiding other FORTRAN related issues, in particular, with the input files that are generated.
194
** SIMC MM
195
*** Very broad and long tail on kaon MM generated by SIMC. Still under investigation.
196
** SIMC High Q2
197
*** There were negative MM and other variables being generated by SIMC for high Q2 settings.
198
*** Likely caused by sigT going negative. By setting some of sigT's parameterization to zero, the issue should be resolved. Still under investigation.

** Most bad runs (i.e. those replays/analysis files that failed for various regions) for Q2=2.1 have been properly run. There are still a few outstanding runs that need to be further investigated.

** Equations for the xsect iteration script have been properly adjusted to match those found in the fortran script of SIMC (physics_iterate.f).
213
** Testing with Q2=2.1 is underway with a minor bug with efficiency calculation that needs to be resolved. Once this is done, this setting will test the xsects iteration and separated xsects scripts.

336 629 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.

** 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.

** 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.

** 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.

** 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.

** 3.6 and 3.9 GeV data do NOT have the angle offsets. This has been established in the study.
1048
** I've plotted the offsets vs SHMS central momentum. Plots are attached in the attached pdf file.

1050
** The 10.6 GeV heep analysis is going well but the broad momentum distributions are making offsets difficult at times.
1051
** 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. 
1052
** 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 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). 
1344
** 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.

* SHMS Reference Time Amplitude Cuts(Stephen)
1688
** Extra peaks in HG from cross-talk and "ghost-bands" due to ADC screw up
1689
*** cuts applied on SHMS ADC ref time amplitude (greater than zero) done before any further event selection and histogram filling
1690
** This is a temporary fix to "ghost-bands" and cross talk
1691
*** Although for HG there is still a small peak. The hodoscope is fine.
1692
** The time window is easier to set now.
1693
** DC has been fine (since it uses TDC)
1694
*** DC calibrations should be good to complete, other detectors need more fixes (i.e. the remaining "ghost-band")
1695
** 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)
1698
** Peter implemented changes to hcana
1699 1 Richard Trotta
** Two major issues...
1700 67 Richard Trotta
## Amplitude goes to null and integral is low or negative which causes a rate-dependent efficiency. 
1701 1 Richard Trotta
*** Peter has used the average pulse value acquired over a large sample of runs for each detector. 
1702 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)
1703
*** Peter created a routine to find the best offset by means of matching TDC and ADC
1704
** Richard has been checking for bugs in the code. 
1705
*** It seems to be ready to implement, Richard emailed Peter for confirmation on the implementation in our group directory
1706 1 Richard Trotta
1707 67 Richard Trotta
* Calibration of HMS detectors when the timing is agreed upon by Stephen and Richard.
1708 65 Richard Trotta
** Besides hodoscope which still has an issue with the script
1709 62 Richard Trotta
** Stephen and Richard are having a meeting late next week to determine time window values
1710
*** These will be relatively final, but on the wider side if adjustments need to be made in the future

1845
1846
* Richard
1847
** 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
1848
** 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)
1888
** Tracking-based analysis for Runs 1415-1423, .. for now focus on HMS, typical HMS S1X rates are <
1889
** Cuts applied: PID for electrons (Cer, Cal), acceptance (delta)
1890
** Efficiency calculation was investigated in detail and applied using scalers from trees
1891
** Results for carbon (normalized to 30uA) show large variation - need to understand
1892
** *Next steps:*
1893
*** Double check calculation of computer lifetime, look for differences in TRIG and PRETRIG scalers
1894
*** Check stability of pre-scale (Ryan saw changes within runs)
1895
*** Check if detector calibrations for runs are implemented correctly
1896 1 Richard Trotta
*** Analyze with Ryan's cuts
1897 35 Stephen Kay
1898
* Luminosity Scans April 2018 (Ryan)
1899
** Confirms Richard's earlier finding that scaler-based analysis is not reliable and that it's best to analyze event-by-event
1900
** Tracking-based analysis for runs 2073-2095
1901
** Cuts applied: PID for electrons (TOF, Cal, Chi2), acceptance (delta and angles), BCM4a
1902
** Included most recent detector calibrations in replay of these runs
1903
** Efficiencies from report file mainly, may need to update tracking efficiency implementation
1904
** Found that calculations of computer deadtime requires different set of scalers for runs from January to those from April 2018
1905
** Results show carbon yields consistent with unity within error (0.5% error bars), and boiling for hydrogen and deuterium
1906 5 Richard Trotta
** *Next steps:*
1907 35 Stephen Kay
*** Check tracking efficiency
1908
1909 1 Richard Trotta
* *Global comments on Luminosity Scans (so far)*
1910 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.
1911
** Efficiencies in report files need to be updated, e.g. CPU deadtime (Richard)
1912
** Check if BCM4a is the one closest to the target - get a map of the hall (Richard, Ryan)
1913
** Uncertainties on current

* eK+ coincidence time from SIDIS Spring 2018 run (Samip)
1918
** Worked with Mark Jones on coincidence time calculation - now available in hcana (see Samip's 10 May 2018 email for more details)
1919
** runs used in this analysis: 3423 with Q2=3.1 GeV2 and W=2.78 GeV
1920
** Coincidence time spectrum shows peak separations >2 ns corresponding to different accelerator frequency
1921
** Missing mass spectra: Kaon peak clearly visible, also see pions even after cuts
1922 1 Richard Trotta
** Found that pions appear localized in phase space - seems to be due to end point in kinematic phase space
1923 2 Richard Trotta
** *Next steps:*
1924 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)
1925
1926
* Yield normalized ratios from SIDIS (Hem)
1927
** Yield ratios of data to MC match well in shape, but normalization seems not quite right
1928 4 Richard Trotta
** *Next steps:*
1929
*** Check if efficiencies, currents, run time etc. are taken into account correctly

* Discussion luminosity scan analysis (earlier scan) - Richard
1938
** 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
1939
** Notes on efficiencies in report file:
1940
*** DT (EDTM) is not electronic deadtime. Instead use for now 50ns* trigger rate for HMS and 100ns* trigger rate for SHMS
1941
*** Cherenkov efficiency seems low (check if that is due to PID, thresholds, pi/e, etc)
1942
*** Tracking efficiency needs to be checked
1943

* Discussion of run plan, and in particular possible low Q2/low energy
1955
** Assume that kaon low Q2=0.4 already included - have kinematics with specified beam energies, if needed
1956
** 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
1957
