In version 2 of the data reduction, we include frames where there is some visible scattered light, but where the background is still reasonably low (not more than a few times the minimum background). ... Briefly, the scattered light subtraction was done by registering the bright and dark images, subtracting the dark from the bright to remove the source, smoothing to remove any residual sources left over after the subtraction, and subtracting this smoothed sky image from the bright frame. ...

... self-absorption - the absorption of light shining on an object by a process similar to that which produced the light originally; if a cloud emits less light than it absorbs from other clouds behind it, this net loss of light, termed self-absorption , causes the foreground cloud to appear darker than the background field (the term is from spectroscopy, where small absorption dips sometimes occur in larger emission lines, making the latter look as if it is absorbing part of itself) . ...
