The integrated photon flux for PrimEx empty target runs (Ebeam > 8 GeV) can be found below (see at the end of this file):
Flux numbers are stored in CCDB tables:
(the same tables, which we use for PrimEx:
/PHOTON_BEAM/pair_spectrometer/lumi/tagh_tagged
/PHOTON_BEAM/pair_spectrometer/lumi/tagm_tagged )
Example of data quality (runs with poor calibration)
Run 30949 (global time shift of the TAGM)
Run 30334 (RF all counters)
Run 30334 (TAGM time)
Run 40903 (TAGH time)
