Report from the last Data Challenge Meeting
Mark created a web-accessible directory for keeping track of data challenge conditions.
Anomalies in MC units
Elliott reported seeing anomalous units in some fields in the raw data. Energies should be in GeV and time in nanoseconds and he is seeing other values. Also negative values of values are sometimes seen, presumably due to smearing.
Work is continuing on code correctness and execution speed.
Curtis suggested that events with electromagnetic background turned on be generated to measure event size.
hddm2root
David described recent work on generating ROOT trees from HDDM-formaterd data. The idea is to do this automatcially from the information in the template included in every HDDM file, with no hand coding. See his slides for details.
There appears to be a limitation of two levels of nesting in the HDDM structure when conversion to ROOT is attempted. David will study this further.
