Due to slightly different optical alignments in each filter, the comet does not fall on the same pixels in J, H, and K. Thus a table is provided to locate the comet in each image. This table gives X,Y positions of the comet in each image. Images without the comet are omitted (ie. sky or standard star). See obs_log.txt for a list of all images included in this archive."
