MR: First approximation. Also put up some pictures generated by TopDrawer.
TJ: Vertexing?
JS: Hacked FastMC to treat unknowns and charge=NAN as neutrinos.
Geant4 returns NAN for charge if unknown.
Right now, treat them as neutrinos.
Had some events with neutralinos that showed up in list of tracks. This hack fixes it.
TJ: Put in PDG IDs for neutrinos. Are these standardized?
JS: Added neutralinos to list.
TJ: Have some PDG IDs in a standard list.
Could fill in correct charge even if Geant4 didn't know about it.
JS: Charge is appearing as INFINITE, not NAN.
TJ: Can compare using INFINITE but not NAN.
RC: Agreed on NAN for LCIO.
TJ: Question at the time whether could write NAN from C++ and read into Java.
JS: ZvTop. Making progress. Can now find multiple displaced vertices. Have to do a lot more checks to see if at right spot and parameters make sense.
Norman and I still have to work on the fitter. Norman worked on porting the C++ fitting code to Java.
TJ: What's wrong with code in ZvTop3?
JS: Looked at it and don't understand. Could try to understand, but just don't understand what it is doing. And not documented. Not derived from a documented algorithm. Did find the program it was based off of, used at SLD. Found page with FORTRAN comments but this is it. New fitter will be based off the BaBar algorithm.
NS: Just completed transition of full CCD simulation into org.lcsim. Debugged and had a hard time finding cm to mm bug. Completing comments to make JavaDocs. It works!
JM: Reported on TestBeam.
MR: Need new properties for a new detector?
TJ: Minimally need the compact description. Event display and browser only need compact. Need certain files for FastMC, etc.
Geometry is one parameter and others are auxiliary.
Could read separate file?
WL: Would be fragile.
Norman was thinking for sid00 to rename the readouts for more consistent names.
Hardwired into Lelaps?
WL: Should not be a problem.
Currently, Lelaps is using sampling fractions = 1.0 in all cases.
RF: SiD cal meeting on Thursday morning. Worth bringing up test beam stuff?
JM: Okay.
WL: Could add flag in LCIO run header whether sampling fractions are available or not.
RC: Could do it, but will get messy. As sampling fractions go beyond one number, will become much more complicated.
Flag if sampling fractions applied would be useful.
