HST (ACS, WFC3, WFPC2) and JWST (NIRCam, NIRISS) imaging, multi-epoch overlap, published proper motions, and Roman / Euclid survey footprints for the 911 dwarf galaxies in the Local Volume Database. Built from MAST on 17 September 2026.

Depth = estimated 5σ point-source AB limit for the deepest single MAST observation in the best filter (sky-limited scaling of ETC reference values; ±0.3 mag; ignores crowding). Epochs = visits to the galaxy separated by more than 180 days. Baseline = longest time separation between two observations whose footprints overlap on the galaxy. Roman footprints: HLWAS/GPS tile maps from Sanderson et al. (2026, arXiv:2603.12981), HLTDS from the Survey Footprint Explorer; Euclid Wide is the published Region-of-Interest definition (|b| ≥ 23°, |β| ≥ 10°, E(B−V) ≤ 0.09), not the executed tiling; Euclid DR1 tiles are ESA's expected-DR1 coverage map (cosmos.esa.int/web/euclid/euclid-dr1-expected-coverage).
