Collection / M81 / M82 · Scope
Faint Structures
Resolved stellar populations and faint substructure around two contrasting nearby galaxies.
M81 · ANGST / GHOSTS
33 overlapping HST ACS/WFC fields.
Approximately 1.89 million raw sources are ingested, with astrometric duplicates removed using a 0.18 arcsec cKDTree match before density-map analysis.
M82 · ANGST
Six overlapping HST pointings.
Geometry-specific masks handle field overlaps. Substructure detection uses a localized median background, Poisson S/N mapping, and watershed segmentation.
