      Description

      ImageDifferenceTask currently supports the option to convolve either the template or the science image, but that option is frozen in the config. For long ap_pipe runs, there may be many visits with a range of seeing both better and worse than the template. While the order may not matter using ZOGY, we are seeing deconvolution artifacts with the current Alard&Lupton image subtraction when the order is incorrect.

            Two questions:

            • are you sure there isn't already an automatic selector? [resolved in group meeting]
            • do we have to worry about measurement error in the seeing? What happens if the science and template images have comparable seeing, so that there's a 50/50 chance that one or the other will be considered "better"?
