Setup
Phase Calibration (per Scan)
# In CASA
listobs("sis14_ampandphase.ms")
# In CASA
os.system("rm -rf phase.cal")
gaincal(vis="sis14_ampandphase.ms",
caltable="phase.cal",
field="0",

# In CASA
plotcal(caltable="phase.cal",
xaxis="time",

plotrange=[0,0,-180,180])
Amplitude Calibration (per Scan)
# In CASA
os.system("rm -rf amp.cal")
gaincal(vis="sis14_ampandphase.ms",
caltable="amp.cal",
field="0",
solint="inf",

# In CASA
plotcal(caltable="amp.cal",
xaxis="time",
yaxis="amp",

Phase and Amplitude Calibration (per Integration)
# In CASA
os.system("rm -rf apcal_int.cal")
gaincal(vis="sis14_ampandphase.ms",
caltable="apcal_int.cal",
field="0",
solint="int",
calmode="ap",
refant="DV22",
gaintype="G")
Plot the per-integration variation of the phase.
# In CASA
plotcal(caltable="apcal_int.cal",
xaxis="time",
yaxis="phase",
subplot=331,
iteration="antenna",
plotrange=[0,0,-180,180])
Now plot the per-integration variation of the amplitude.
# In CASA
plotcal(caltable="apcal_int.cal",
xaxis="time",
yaxis="amp",
subplot=331,
iteration="antenna",
plotrange=[0,0,0,0])
