EM DATA TAKING CONFIGURATIONS
04-Feb-2003
Configuration 1 Main calibration run
Configuration 2 Control sample and transition from vertical to horizontal set-up, to make sure everything is working OK.
Configuration 3 Main Photon run
Configuration 4 Run to validate the input spectrum not the LAT design. Requires the CAL-LO trigger to be changed to about 4 MeV/crystal (which is about 5 sigma away from the noise ?). We have already investigated with ELX and I&T online that DAC settings can be individually set.
