A 2003 XMM-Newton observation provided the data for this catalog of X-ray point sources in the starburst galaxy NGC 253. The HEASARC created this table in April 2009 based on published research, which includes spectral fits for the brightest 140 sources and an analysis of ~100 likely contaminating sources. The catalog compares luminosity estimation methods and assesses background contamination from foreground stars and background galaxies.
