Announcements
• digitizations will be needed to make simulated data for online testing, need to start discussion • elliott will write up requirements for this
Igor, richard is working on the code, need a report from him,
database, magnetic field maps
panda central tracking tdr, curits linked to agenda
simon: chisq problems, track finding stage, could be improved forward direction number of candidates with wrong charge hypothesis, chisq of fit is bad mark: may be a marker, not a cause
Will, BCAL, doing ok for single photon events, moving toward 1234 segmentation, work in progress
1234 can be changed easily, matt, calibration may not be correct, geometry file to change segmentation
Paul, item 5, wiki page • uncertainties on bcal fcal tof • single photon, pion events • compare reconstructed vs generated
need convention for time reported for all detectors, inner radious, front face
tracking simon pid paul photon matt
brainstorm
many more reconstructed
0 - 10.5 degrees
big overshoot at downstream end of bcal Beni's b1pi wiki page
number of protons, reconstruction efficiency seems very low compared to pi + at angle of 30 see same amount of protons and pions
will thinks taht the problem was not as bad a few months ago
new segmentation for the bcal
overall reconstruction in b1pi
cause of complete failure of track fitting and finding
particle id timing shift in time of flight timing shift in fcal
paul will present a design for how tof beni present hermes scheme
mark will add items to list conveners will organize the list
