The on-sky footprint of the Roman survey with archival z-band imagery from Pan-STARRS1 (Chambers et al. 2016). Bad pixels in the Pan-STARRS1 data are colored in white and are used to flag saturated sources, areas without survey coverage, etc. Left: the full survey footprint, covering ∼2 deg2 of the Galactic bulge over seven fields. Field outlines are shown in orange. Middle: a single field, with outlines of the 18 detector pointings shown in orange. Right: one detector within this field. Field pointings were taken from Penny et al. (2019;
