Local Normalization Exclusion Question

Edward Smith
in PixInsight
I just finished Video Set 31 in the Fundamentals Path (the WBPP Mono Integration with Interactive LN that has 2 Parts) and I'm not quite sure what the program was doing with your input.  In Part 2 where you were doing the Interactive Choosing for the Local Normalization, you excluded some of the frames from some of the datasets (in fact, you excluded several in the Luminance channel).  However, when it actually integrated the frames, it looks like the excluded frames were included.  So what does "Exclude" mean in this context?  Just that it isn't eligible to be the master frame that is used for LN (or to be included in the Integration for the Master Frame) but it has no effect on whether the frame is used when the entire data set is Integrated?  It kind of looks like that is what happened, but I'm not positive.

Thank you.

    Hi Edward,

    When you exclude a frame, another frame (the next one a the "bottom" of the best frames) will be included. So the total number of frames being used to integrate together will be what the chose "Frames" number is in play.

    In the case of the Luminance I excluded a few frames that had satellite trails. It really was not necessary..but it did show how to do it. The excluded frames were not used when I pressed the "generate" button. Only the frames with the check mark are used.

    Remember... this stacking is just to create a single LN reference frame. You can use just one frame..and several to average things out. This doesn't have anything to do with the stacking of the full set of light frames.

    Adam,

    I don't think my question was really clear, but I think your last sentence answered it.  I'm going to rephrase your answer so you can tell me if I heard correctly.  The "Exclude" here was a local exclusion related to LN reference frame creation and had no meaning outside that reference frame creation process.  Do I have that right?

    Thank you.

    Yes, correct.
