** SIMC code was updated to match what is in hcana, using hcana and parts of Carlos' code as a template. Things do not look right though. 
143
** We are a month behind at this point and Bill has finally responded to my questions so I am going to fully concentrate on getting cross sections before the Hall C collaboration meeting in January so that Nathan can present them. I am setting a soft deadline of January 6th to get him early results but will continue to push for cross sections by the talk.

161
** Plots of right/left/center for each physics setting have been added, including efficiencies and t-bin plots (no diamond cuts yet!). These plots show the input to Bill's code for comparison. These need to be updated with Ali's updates so a new set of replays will need to be analyzed.
162
** Bill is doing a write-up with some questions I had which will hopefully fix the remaining issues I've been having with his code.

** 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.
187
** 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.
188
** I found a script for raster calibrations. The script is being fixed as it is currently a bit of a mess.

** 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.

** 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%.
234
** 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.
235
** 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.
267
*** It should be noted, there are huge discrepancies between BCM4A and BCM1 in some cases (like 20+ uA).
268
** Ran into some issues with the cross-section code. I am in debug mode trying to find the cause.
269
** Tanja sent me some awesome fpi2 raster correction documents as well as procedures for verifying the beam and target positions. I am in the process of reading through/beginning these procedures. A Redmine wiki page will be linked when completed.

** 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.
337 370 Richard Trotta
** I've plotted the offsets vs SHMS central momentum. Plots are attached in the attached pdf file.

339
** The 10.6 GeV heep analysis is going well but the broad momentum distributions are making offsets difficult at times.
340
** 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. 
341
** 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.

## Amplitude goes to null and integral is low or negative which causes a rate-dependent efficiency. 
990 67 Richard Trotta
*** Peter has used the average pulse value acquired over a large sample of runs for each detector. 
991 1 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)
992 67 Richard Trotta
*** Peter created a routine to find the best offset by means of matching TDC and ADC
993
** Richard has been checking for bugs in the code. 
994
*** It seems to be ready to implement, Richard emailed Peter for confirmation on the implementation in our group directory

1133
** resolving differences between his analysis and Richard's
1134
1135
* Richard
1136
** 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
1137
** 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 (Richard, Ryan)
1152 111 Richard Trotta
** Carbon scan from April seems consistent with no boiling, LH3 and LD2 show deviation from unity, should check effect of EDTM events on efficiencies
1153 35 Stephen Kay
** 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
1154
** discussion about pre-scale factors
1155 1 Richard Trotta
1156 35 Stephen Kay

1161
** Optimal range is between electron angles of 17-20 degrees, time required ranges from ~1 hour at 17 degrees to ~3 hour at 20 degrees, other angles may be of interest for disentangling charge and current dependent effects

1176
* Luminosity Scans January 2018 (Richard)
1177
** Tracking-based analysis for Runs 1415-1423, .. for now focus on HMS, typical HMS S1X rates are <
1178
** Cuts applied: PID for electrons (Cer, Cal), acceptance (delta)
1179
** Efficiency calculation was investigated in detail and applied using scalers from trees
1180
** Results for carbon (normalized to 30uA) show large variation - need to understand
1181
** *Next steps:*
1182
*** Double check calculation of computer lifetime, look for differences in TRIG and PRETRIG scalers
1183
*** Check stability of pre-scale (Ryan saw changes within runs)
1184
*** Check if detector calibrations for runs are implemented correctly
1185
*** Analyze with Ryan's cuts
1186 1 Richard Trotta
1187 35 Stephen Kay
* Luminosity Scans April 2018 (Ryan)
1188
** Confirms Richard's earlier finding that scaler-based analysis is not reliable and that it's best to analyze event-by-event
1189
** Tracking-based analysis for runs 2073-2095
1190
** Cuts applied: PID for electrons (TOF, Cal, Chi2), acceptance (delta and angles), BCM4a
1191
** Included most recent detector calibrations in replay of these runs
1192
** Efficiencies from report file mainly, may need to update tracking efficiency implementation
1193
** Found that calculations of computer deadtime requires different set of scalers for runs from January to those from April 2018
1194
** Results show carbon yields consistent with unity within error (0.5% error bars), and boiling for hydrogen and deuterium
1195
** *Next steps:*
1196 5 Richard Trotta
*** Check tracking efficiency
1197 35 Stephen Kay
1198
* *Global comments on Luminosity Scans (so far)*
1199 1 Richard Trotta
** 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.
1200 35 Stephen Kay
** Efficiencies in report files need to be updated, e.g. CPU deadtime (Richard)
1201
** Check if BCM4a is the one closest to the target - get a map of the hall (Richard, Ryan)
1202
** Uncertainties on current
1203
** Detector calibrations
1204 1 Richard Trotta
** HMS vs. SHMS
1205 35 Stephen Kay
1206
* eK+ coincidence time from SIDIS Spring 2018 run (Samip)
1207
** Worked with Mark Jones on coincidence time calculation - now available in hcana (see Samip's 10 May 2018 email for more details)
1208
** runs used in this analysis: 3423 with Q2=3.1 GeV2 and W=2.78 GeV
1209
** Coincidence time spectrum shows peak separations >2 ns corresponding to different accelerator frequency
1210
** Missing mass spectra: Kaon peak clearly visible, also see pions even after cuts
1211
** Found that pions appear localized in phase space - seems to be due to end point in kinematic phase space
1212 1 Richard Trotta
** *Next steps:*
1213 2 Richard Trotta
*** Look for a run with kaon momentum closer to 3 GeV/c (aerogel threshold is ~3 GeV/c for kaons for n=1.015)
1214 35 Stephen Kay
1215
* Yield normalized ratios from SIDIS (Hem)
1216
** Yield ratios of data to MC match well in shape, but normalization seems not quite right
1217
** *Next steps:*
1218 4 Richard Trotta
*** Check if efficiencies, currents, run time etc. are taken into account correctly

1226 35 Stephen Kay
* Discussion luminosity scan analysis (earlier scan) - Richard
1227
** 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
1228
** Notes on efficiencies in report file:
1229
*** DT (EDTM) is not electronic deadtime. Instead use for now 50ns* trigger rate for HMS and 100ns* trigger rate for SHMS
1230
*** Cherenkov efficiency seems low (check if that is due to PID, thresholds, pi/e, etc)
1231
*** Tracking efficiency needs to be checked
1232
*** 3/4 trigger efficiency seems ok
1233
* Discussion luminosity scan analysis (later scan) - Ryan
1234
** Fewer carbon runs than earlier scan
1235
** Shown is a tracking-based analysis using data from the ROOT trees
1236 111 Richard Trotta
** First results for carbon, LH3, and LD2, but efficiencies need to be checked
1237 35 Stephen Kay
* SIDIS analysis - Hem
1238
** Shown is a data/MC comparison for different kinematic settings. Agreement in shape is very good. Normalization has yet to be applied.
1239
** Discussion about agreement in z and apparent offset - relation of this offset with spectrometer offset
1240
* Analysis of exclusive events in SIDIS - Samip
1241
** Shown is a look at the first kaon events in exclusive limit of SIDIS data
1242
** Ongoing work on implementing coincidence time into tree
1243
* Discussion of run plan, and in particular possible low Q2/low energy
1244
** Assume that kaon low Q2=0.4 already included - have kinematics with specified beam energies, if needed
1245
** 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
1246
** Garth will put this together in a draft email

1265 35 Stephen Kay
*  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.
1266
* Brief description of Samip's work - working on coincidence timing decoding with JLab staff and re-optimization of kinematics
1267
* Discussion of Richard's slides on run plan kinematics and preparations -
1268
** 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
1269
** 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
1270
** for each setting will need 1-2 shifts for calibrations - need to negotiate with other experiments in run group
