Similar as reference complex gain calibration, daily gain calibration refers to tuning the "system" amplitude and phase as a function of IF band at a finer level. Typically, daily gain calibration would be carried out three times between two reference gain calibrations every day. I have a routine to retrieve and analyze the daily gain calibration data, named phacal_anal.py. Start from a timestamp

import phacal_anal as pa
from util import Time
t = Time('2017-07-03 15:00')
pa.phacal_anal(t)

phacal_anal will find all daily gain calibrations occurred during that natural day (CA local time). to be completed...
