PS acceptance and luminosity determination
From GlueXWiki
Pair Spectrometer acceptances were measured using runs with the total absorption counter. The shapes were compared with the detailed Geant simulation.
The normalization of PS acceptances agrees reasonably well, on the level of 5%, for 2018, 2017, and 2016 TAC runs. Note, the acceptance shape for 2016 data
is different due to the larger PS magnetic field. A good agreement in shapes between the measurements and simulation was observed.
