Notes

dmitry coming in middle of june

dphoton, dfcal shower inconsistency between bcal and fcal mij was going to change fcal to match bcal hits from detectored, cluster, showers, particle associated with vertex M.algorithm to merge showers, should be later after matching showers with charged tracks propose to make this change fcal photon obsolete, will be shower, have energy and position in fcal

paul missing a whole bucnh of particles fixes were done to the vertex factory photons were 0 momentum and energy improved if not fixed re-ran b1pi analysis last stable build was getting 5% reconstructed high mass tail to unphysical values new, was not there 3 mos ago pi0 now wider than before

vertex factory, where particles are grouped, charged and photons, cut hard-wired at 3 sigma, time and z, things were grouped into different vertices, several

vertex structure, class, member of dvertex, hold shower, inherits from dkinematic data, pointers to cluster objects, reconstructed info, not copied into dkinematic data part. info now copied into dkinematic data infinitely large cut, 100 sigma, a configuration parameter veryy good bulshitters
