Daily Gain Calibration
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. We have a routine to retrieve and analyze the daily gain calibration data, named phacal_anal.py. Start from a timestamp (Note: The time of day is important! Make sure to set it to somewhere in the middle of the day, e.g. 15:00 UT)
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).

First run the refcal for the day:
from util import Time import refcal_anal as ra import cal_header as ch out = ra.rd_refcal(Time(['2017-08-21 11:00','2017-08-21 14:00')) out_corr = ra.unrot_refcal(out) refcal = ra.refcal_anal(out) ch.refcal2s
