Convert color source fits to color jpg
Two-point register and rectify image in LTVT
Export rectified color jpg to file
Obtain solar angle and azimuth, observer's sub-Earth
latitude and longitude, feature position latitude and
longitude, and compute image scale
Convert color source jpg to 8-bit or 16-bit greyscale fits
Rotate the image so the apparent solar azimuth is 270°
Crop the image
Resave the image as an 8 bit or 16-bit greyscale fits
Export the greyscale image to an NxM csv matrix
