Extended Data Table 1 Luminosity model of M60-UCD1

From: A supermassive black hole in an ultra-compact dwarf galaxy

  1. This multi-Gaussian expansion model is composed of 23 Gaussians based on the F475W-band Hubble Space Telescope/ACS image. The position angle of the galaxy is −49.45°. The apparent surface brightness (solar luminosity per square parsec) has a correction for galactic foreground extinction (0.087 mag)50, and assumes a solar luminosity in the g band of 5.12 mag. logσ′ is the projected size of each Gaussian on the plane of the sky along the major axis. q′ is the projected flattening (the axis ratio of the short to long axis).
