The integrated photon flux for PrimEx empty target runs (Ebeam > 8 GeV) can be found below (see at the end of this file):

https://halldweb.jlab.org/primexd/data_quality_2019/quality_check_2019.pdf


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) Run30949

Run 30334 (RF all counters) Run 30334

Run 30334 (TAGM time) Run 30334 (TAGM)

Run 40903 (TAGH time) Run 40903 (TAGH)
