In this work we report on two sets of measurements involving the Hall-B photon tagging system of the Tomas Jefferson National Accelerator Facility. The relative energy calibration of the tagging counters was performed by using the PrimEx pair spectrometer and a series of high position resolution micro-strip detectors. The photon energies were determined by forming coincidence between the tagger and the e+ e- pairs for several values of the pair spectrometer magnetic field between 0.36T to 1.9T (total of 180 fields). The second set of measurements, collected in conjunction with the Fall 2004 PrimEx run, investigated inherent limitations on the photon tagging technique. We report for the first time an experimental signature for these effects.
