We present the X-ray luminosity function (XLF) of the Antennae galaxies based on 8 observation performed with Chandra. We detect between 37 and 49 sources in each observation. After combining all observations we detect a total of 120 sources down to a limiting luminosity of ˜ 2x1037 erg s-1. Comparison between the XLFs of the individual observations shows that they are not affected by source variability. The cumulative XLF of the coadded observations is well represented by a single power-law with a slope of ˜ - 0.5.
