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
