Summary of Meeting Discussions:
All. Nominate secretary: Dustin McNulty
All. Approval of last week's minutes: Itemized below
1: LMS, ped; clock skims are done with the exception of a few here and there. May need to redo ped skims because there are EPICS events in them -- Mark will look at this. Also, Dustin will check with Dave L. about EPICS skim (e.g. What trigger do the EPICS events carry).
2: Ilya says MOR prescaled events represent ~1.2% of total events (for one particular run), but it varies a bit.
3: Physics skim--Mark will do the farming, Ilya will assist with cuts definitions and code.
4: Aram volunteered for writing the time-access routine.
5: HyCal timing -- Eric -- Goal is to push a standardized timing scheme to CVS for all analyzers to use.
6: HyCal energy resolution. approved...
All. New Business: Itemized below
1: LMS event collection inefficiency -- only 700 out of 4000 events collected during phase 2 (LMS phase) are "true" LMS events, the remainder are essentially pedestal events (for HyCal) due to the logic of LMS trigger. It was done this way so we could acquire YAP (alpha source) events from the 3 LMS reference pmts. We all agreed that this is far from ideal and that it must be addressed before our next run.
2: At what level can we keep our experimental apparatus (Hycal, DAQ, etc) working? This is necessary for a smooth startup during our next run. ***IMPORTANT***
3: Dave L. needs to give explaination of livetime and deadtime-crrection.
4: Book Keeping -- As a start, Dustin will create a uniform scheme for tracking the various types of good runs using database.
5: We need to go to the next level (in complication/accuracy) of our Clustering Algorithm. It was proposed that we should setup different algorithms (7x7, 6x6, 5x5 with extension) to test which gives best results. We should also incorporate Vasily's algorithm for overlapping cluster separation and apply a shower profile chi2 cut. Dustin and Ilya will work on this.
6: Our analysis software needs Multiple Output Streams; Mark will talk to Dave about this.
