This is a summary page with the progress of the KaonLT experiment. Above is a quick outline of our current progress. Below are tasks assigned to members of the group. Anyone who is part of the group may contribute to a task with suggestions and/or updates on progress. Please contact the assignee on a task-by-task basis for any queries. Anyone with general questions can contact Richard Trotta (trotta@cua.edu).

* In Fpi-2 it drifted with TDC temperature and needed to be adjusted on a run-by-run basis to within 200 ps.
58
* Initial checks so far indicate the peak is stable. Cointime resolution will be poorer in fall 2018 run due to DAQ cabling issue. Mark has partial software fix that we need to be sure is implemented.

* This replay should include all new kinematic offsets, better timing and PID calibrations, as well as Mark's most recent HMS and SHMS matrix elements.
161
* Quality control rechecks with new replay:
162
** carbon luminosity scans are flat vs. current and rate
163
** LH2 luminosity scans are flat vs. current and rate
164
* HMS saturation corrections?
165
* Final investigation of SHMS acceptance, optimize acceptance cuts based on sieve-slit run analysis, agreement with single-arm MC. 
166
** Compare data and simulation plots of SHMS yfp,ypfp for various ytar,delta bins to identify inconsistencies.
167
* Trigger blocking studies.
168
** Are extra factors needed to correct for missing FADC reference times, or any other DAQ related effects?  Initial info from Peter Bosted indicates this is likely to be the case.
169
* Recheck Heep singles and coin yields to identify and fix problems.
170 1 Richard Trotta
* Stability checks.  Need some scripts to look at invariant mass vs run number, etc., for pi+/K+/p channels.
