This is a single 2 hours exposure image at Feb 2 coordinates. I also scaled the 1 hour dark to 2 hours using a small program that I made. I used a factor of 1.98, which is based on the difference between the 20 and 60 minutes darks. Arnie also calibrated the image for me because IRIS truncates high pixel values before doing multiply/subtract.
