Minutes
jlab mark david simon elliott sascha iu matt mikhailo
doxygen generation svn statistics
particle factory
bcal fcal charged tracks track matching to outer detectors beta from time of flight particle ID a mass is assigned uses time based tracking results sascha: want to go back to original objects david: associated objects dphoton: tries to use track information as well dparticle name was used by dtrack-time-based
dphoton calculates error matrix in lab frame need event vertex factory needed to generate the dphoton object now uncertainty of the vertex location folded into error matrix accessing fits for various mass estimates
sasha: pid likelihood
cleo: pi k proton fit entrance fits, exit fits
dphoton should use dtrack-time-based for neutral identification
should we use wire-based or time-based for track matching
design to be presented at next meeting
