Sunspot Band6 Feathering for CASA 4.7

Overview

This portion of the Sunspot Band6 CASA Guide for CASA 4.7 covers the combine process between the synthesized solar image and the full-sun image obtained with TP array. It begins where the calibration of the visibility data and single-dish data, image synthesis, and creating of the full-sun map are completed. If you do not complete them, at first,

1) Download the file of the un-calibrated data package ‘Sunspot_Band6_UncalibratedData.tgz’, do the calibration of the data, and create the images from the interferometric data and single-dish data, along with the ‘Sunspot_Band6_*_for_CASA_4.7’ tutorials.

or

2) Download the file of the calibrated data package ‘Sunspot_Band6_CalibratedData.tgz’, and synthesize the image from interferometric data along the ‘Sunspot_Band6_Imaging_for_CASA_4.7’ tutorial.

In case 1), we assume that you are working on the working directory ‘Sunspot_Band6_UncalibratedData’. On the other hand, when you started the tutorial from the calibrated package (case 2), we assume that the working directory is ‘Sunspot_Band6_CalibratedData.’

From next, we will show all commands for combining the images. If you do not want to cut-&-past the commands, you can use the script as described in #Alternative way of Combining Images.
