Notes. The RA and Dec uncertainty is calculated as the square of the quadratic sum of the errors in RA and Dec and corresponds to ~1 standard deviation uncertainty. The flux was calculated with edetect_chain using the conversion factors mentioned in the text. For source X2, the flux calculated directly from the detailed spectral analysis is given instead, since it is very faint and the photon index of its spectrum is 2.6. The sources X8 and X9 were additionally detected with ewavelet. The extension mentioned for all sources results from the tool ewavelet, even if the radial profiles of some faint off-axis sources (such as X2) are compatible with a King profile. The CXO names of the sources detected with Chandra are given as well.
