For each DR1 field, the median match distance to Pan-STARRS1 for the stack catalog compared to the the standard deviation of median match distance for the individual exposures. The sources are colored by the absolute value of their Galactic latitude. The match distances in the individual images have a subpixel deviation of at most 0﹩\mathop{.}\limits^{\unicode{x02033}}﹩1, and we see a decrease in match distance near the Galactic plane.
