The barrel calorimeter, BCAL, is one of the primary and integral detectors used within the GlueX experiment, based in Hall~D at Jefferson Lab. It records the time and energy deposition of impinging neutral and charged particles, following a high-energy photon-proton collision. Light produced by hits in the BCAL is collected by silicon photomultipliers, SiPMs, fixed at each end of its cylindrical structure, and which provide a readout for each layer. The ADC gains for the BCAL SiPMs in each readout cell, along with four other sets of calibration constants, were accessed using CCDB and were compared for each run period within Phase I and Phase II of the GlueX experiment in order to ensure the historical pattern of the constants has remained fairly constant. This is imperative for maintaining the integrity and accuracy of the experiment.
