Report for galaxy #778700818 by Darmok Jalad

Would appreciate some guidance on how to treat structures that appear in the composite image, but not in the individual light channels. Galaxy 778700818 has a bluish region extending upward in the image that’s a very different color from the rest of the galaxy, and that’s not in the individual light channels. The computer approximation included it; I’ve edited the colored segment to ignore it. Can you tell us which is correct?
