UPDATE! Please visit John Murphy's website to download the script. It is no longer part of the official distribution but can be obtained by following the link.
John is now (2023-01-20) making his own YouTube videos on NSG. (I wonder who inspired that!)
The NormalizeScaleGradient script, by John Murphy, is a leap forward in obtaining optimal Integrated images. By allowing this script to normalize images through a robust photometric method of determining scaling factors between images, the results yield sensible image weighting, improved pixel rejection and a simplification of co-added (averaged) gradients. The sections below are for members of Fundamentals- a fuller demonstration and explanation of this script is in Horizons.
