Sunspot Band6 SingleDish for CASA 4.7
Overview
This portion of the Sunspot Band6 CASA Guide for CASA 4.7 will cover the calibration and imaging of the data obtained with the TP array.
From next, we will show all commands for the calibration and be creating the map of a full Sun with Band6. If you do not want to cut-&-paste the commands, you can use the script as described in #Alternative way of the Calibration and Imaging of TP data.
Import the data and split into the files for each antenna
We assume that you already complete the calibration of the visibility data along the Sunspot Band6 Calibration for CASA 4.7, and you are working in the directory ‘Sunspot_Band6_UncalibratedData’. After starting CASA, we start by defining the directory name of the ASDM and Measurement set for the calibration.
#In Casa
sduid ='uid___A002_Xae00c5_X2e6b'
sdmsd = sduid + '.ms'
ant = ’PM03’
In the tutorial, we will use the data obtained with the PM03 antenna.
Before we can proceed to the calibration, we will need to convert those data to the CASA MS format. This is done simply with the task importasdm.
#In Casa
importasdm(asdm=sduid,with_pointing_correction=True, verbose=True,vis=sdmsd,overwrite=True)
The usual first step is then to get some basic information about the data. We do this using the function ‘sd_scantable’, as follows. <source lang='python'>
- In Casa
scans = sd.scantable(sdmsd, average=False) scans.summary(filename=sduid+'.summary') </ource>
