Software Review Preparations
no committee, no charge friday weekly meetings matt, eugene, curtis, david, mark in communication with clas12 curitis: understanding among ourselfsv swereh we wstand what has to be done what manopower will it take where are we thin Rolf leading effort ot get collaboration between halls meeting planned for a week from today next wed. 14, 3:30 division level meeting halll leaders meet, graham selected topics online systems halld will not focus on the online as a planning strategy some assignments from rolf done tracking clara vs jana to do
single event display
monitoring histograms
Reconstruction Subgroup Reports
calorimeters
will, put aside bcal, looking at fcal photons in b1pi events where are extra photons coming from start from note from mihailo on fcal reconstruction looks at photon that convert pre-cal and not reconstrcution eff for non-convertors above 1 gev 98.6% efficient big drop off below 400 MeV definition of unconverted: includes tof extra photon problem only allow one cluster per track match hadronic showers give multiple clusters allow multiple clusters to vbe vetoed
the match radious made wider more agressive matching reduces average photons per event,
paul will implement wills two bullets
bcal work, not default data model lchanged, can write out energy weighted time spectra, light as a fucntion of time, pulse shape simulation, extgract threshold crossing time mcsmear runs 15 times slower, events 50% bigger record down to kev, record as a string discussion at collaboration meeting, need for realism,
Simon tracking
from tracking meeting, issue with track finding with decaying lambda, vee's, confusion of assositona of hit setnemts, extra track candidates simple altorigthm for dealing with this problem puts all hits into bit patterns compare bit patters, if too many hits in common, trigger algorithm
pid, paul
email yesterday on lifesaving cosmetic changes to pid checked into separate branch, renameing things Dcharged track hypothesis some code is broken hdview broken beni volunteers fir hdview will suggested covariance for neutrals at shower level, not at particle level incorporate
new release
consensus new one now
TDR
old TDR had a pwa section, offline software, general philosophy, high level summary of software, look at what was in there in 2004. David volunteers to look into it.
