Description The PHANGS-MUSE Nebular Catalogue is based on MUSE integral-field spectroscopy of 19 nearby (z=0) star-forming galaxies. The release includes 30,790 reliably identified ionized nebulae (31,399 source total), primarily HII regions, with integrated emission-line measurements and derived properties such as extinction, metallicity, ionisation parameter, and environment.
