I have used your new formula, but keep getting this error message. It does sort out the data, but not sure if the formula is missing something. Here is what I pasted in 1/(Math.abs(Math.min(StarsSigma+1,0))+1) *SNRWeight   and below is the error message. It has a ? before the second Math

*** Error [133]: SyntaxError: syntax error

1/(Math.abs(?Math.min(StarsSigma+1,0))+1) *SNRWeight

    Strange....not getting that error any longer, but I don't seem to ever have any x ed out images.

    I guess that's because I have nothing in the Approval box. I thought perhaps, what you were showing eliminated the need for anything in approval, but apparently not true. When I add this in approval I do get some rejections. FWHM <6 && Eccentricity <= 0.6 Your tutorials sure get my brain going at full speed.

    I think I figured out what I was missing. I believe you are not worried about eliminating images. Your formula for weighting doesn't eliminate frames it just provides how much weight is given to each image during integration, based on the factors you discussing in the video. It implies that each image has some useful information in it, but that information is not equal from image to image. We don't necessarily need the approval part of the process.

    Yes... This section is a specific topic on weighting- because of the inherent problems with SFS especially with SNRWeight.
