Demonstration of the automatic scaling value. The rows present different scalings, with the top row being a linear scale (equivalent to a scaling value a ≪ 1), the middle row using a constant scaling value of 78 (the median of the automatic scaling values), and the bottom row using the automatic scaling value (which fixes the output noise level to 0.2). For the bottom row, the determined scaling values are given as an inset for the different galaxies. The columns show three different galaxies, which from left to right have an increasing S/N (and thus an increasing scaling value).
