Color calibration and slope
Can someone explain to me what we are trying to achieve by adjusting the slope values when doing star color calibration? Would it be possible to see some images of before and after. I have watched some videos on this but doesn't really show what the goal is here; meaning, are we trying to create a tighter star group? or do we want the graph scale to be 1:1 so the plot plot line is at true 45 degrees, or ?? I hope this makes sense, just confused on how we use slope adjustments to make a better color calibration. Thanks!!
So here is a post with some extra information about it. It's a bit older but still applies; https://www.astropixelprocessor.com/community/tutorials-workflows/star-color-calibration-1-58-completely-red-now/
Basically the slopes sometimes need to change as filters can introduce an offset in what we expect to be a black body signal from the stars.
