I’m planning an observing run for this fall with HSC, and we are considering using large offsets in position angle (say, PA=(0,180) or PA=(0,120,240)) for each of our observing blocks to reduce the effects of the CCDs with unavailable channels .
My concern is whether this will cause us problems in the data reduction. I’m currently using version 17 (last major release). Is there any reason to expect that the pipeline will have trouble combining exposures with large differences in position angle?
Thanks for any input!
