Posterior distributions of the antenna amplitude gain factors for the 5 GHz epoch on day 4829. These are incremental corrections, after applying the T_sys, gain-elevation curves and global amplitude scaling (based on self-calibration of M 81*) to the data. Tick marks are separated by intervals of 0.1. Dotted lines mark the value of a unity gain factor. The histogram for MK has been cut for gains < 5, for clarity.
