Create post-stamp images for Subaru data taken in November/December 2020

I have posted examples (log scaling) for each of the arc lamps analyzed. In the top row, the defocus is -4, -3.5, and -3 mm. In the middle row, it is -1, 0, and 1 mm. Bottom row: 3, 3.5, and 4mm.</p> <p>No obvious problems are seen and I will proceed with the analysis of these imags.</p> <p>For completeness, I am also posting the image ``Subaru_LAM_comparison'', which shows differences in the illumination between Subaru and LAM images. It is not obvious to be what is happening here and is this a reason for concern.</p> <p>I am reopening again because I discovered that some poststamps were the central spots images were saturated failed. I am going to take some new data with shorter exposures and see what I am doing wrong at the moment. These images were so saturated that they would not be useful for analysis.</p> <p>Two improvments:</p> <p>1. Code has been upgraded so that it does not fail with saturated images. The problem arose because I was passing mask values from the DRP into the code, and before I was only passing the mask with only possible values being 0 and 1.</p> <p>2. I have also substituted the images which were oversaturated with images taken with shorter exposure times.</p> Blocks PIPE2D-490 Relates PIPE2D-671 PIPE2D-487 PIPE2D-614 Development Rank 0|02qps2:v Sprint 2DDRP-2021 A Story Points 3.0
