Description

Initial data acquisition of 15x600s for each channel.

Initial stacking in CCDStack. In the blue sub-frames I had 38 satellite trails. I have reprocessed the image using classic rejection settings and mean combine. I then created a standard deviation combine that included the satellite trails. I then subtracted the standard deviation file from the mean file. The results are better..

My strategy to cope with SpaceX is to dither a lot more (some of the trails were 8 pixels wide) and continue to explore CCDStack or PI rejection techniques.

Only other processing was DBE in PI.

I plan to acquire another night of two worth of data and re-process. I will include L sub-frames in a future image.
