This screen capture shows the intensity histogram of the RED master flat frame. There are no nodes in the histogram as seen in the SII and Ha but the distribution is wider than the LUM with perhaps a weak hump on the trailing side. The bulk of the variation is due to slight vignetting but there is some evidence of a weak interference/diffration/reflection node.
