The Difference column (CSM -> ISIS) represents the mean difference in pixels from running usgscsm's *image2ground* and then back to the camera using ISIS3's *campt* (ground2image). The Difference column (ISIS -> CSM) is simply the reverse starting with ISIS3 first with *campt* (image2ground) and then usgscsm's *ground2image*.
