- chi : result from before/aft resistor change show little difference
even if number of hits increased.
- doug wire-plane eff close to 98% (if box is on!) before looking at tracks
- need to check if above efficiency with tracks (ca 70 % of tracks should've 18
hits..). Jason preparing code for doing this (calculated distance track/wire
to determine if wire should have fired)
- We still have to study accuracy for ideal tracks only, vs # hits, vs FF routine
- Best done with upcoming DST (chi, hpefully this we)
- DST has to be part of the tag, still fixing reconstruction problems
- A next task is to parametrize wch/recon eff vs box number
- needed for meaningful comparison with mc
- doug preparing geographical map of boxes
- MonteCarlo:
aron: preparing code fo rsub-detector (read in geom, add
shift, spit out new geom file). Will be in blast_params.
detector model still missing. Will come eup in the next meeting's
agenda.
- tdc offsets:
_note from tb, pk coming up. There was a conceptual error in the analysis
(or rather, how we tought things were cabled)
_ may explain why offsets never really worked
_ needs to re-analyze bunch of runs, check with pk to for new cal file
- cal file will now depend on trigger downloaded! (or actual retime delays)
_ libBLAST will read fname from db.
- cal file need to be archived.
********** Next meeting friday AFTERNOON (after committe visit)
Agenda:
_ status of reconstruction
_ montecarlo outer detector model
_ status of cal files
