Last week, Patel took a test strip of galaxy prints made with different RGB-to-CMYK conversions for C-printing and we analyzed the results. Today I used the results of that to make a refined test print, with a finer grid centered on the best results from last week's test. The idea is to do a RGB-to-CMYK conversion that respects the physical properties of the CMYK inks, such that the reflectance of the CMYK print is related in a sensible way to the intensity of the RGB image on a standard monit

... spent part of the morning talking to Mykytyn and Patel about the Sloan Atlas. We have awesome two-d image fitting working on Messier-sized galaxies (the hard ones) and everything looks great but we are having trouble interpreting the output! I fixed a monster bug in the code and nothing changed. This isn't atypical: A huge bug can be fundamental and insane but not actually flow down to different results. That makes me fear for the correctness of the results from almost every large scienti

... extremely detailed visualizations of the detected photons in the space of time, RA, Dec, detector position, and charge-pulse amplitude. It is in these signals—or really their departures from expectations—that we will see issues with the spacecraft attitude model, the detector sensitivity map, and the point-sprea
