My observatory partners and I have a camera that is very sensitive but has an annoying number of troublesome columns. These are not simply dead or stuck pixels but instead they are slightly brighter or darker than they should be and are difficult to detect programatically. Neither have we had any luck calibrating these out with darks and biases. The best solution so far has been to do column repair. This is a topic that Bud Guinn addressed several months ago on this forum and that Ioannis delivered the fixLines.js script to address. This script works well on our images but I wanted to make it a little more convenient to run on a large number of images and I wanted an easy way to enter and store the defects with my data for later reuse.
BatchRepair is based on Ioannis Ioannou's fixLines script and Juan's text file reader posting. It takes a list of input images and a text file that lists the bad columns and rows. For example,
I find that using a standard text file for input is very convenient. Maybe someone else will find it useful. In addition to the script I have attached a screen shot of the popup for the curious.
