Table 1: X-ray sources detected in our EPIC images of NGC 6383. The first and second columns yield the number of the X-ray source as well as the name according to the naming conventions for serendipitous XMM-Newton sources. Columns 3, 4 and 5 provide the vignetting and background corrected EPIC-pn and MOS count rates in the 0.5-10.0 keV energy range, whilst Cols. 6 and 7 yield the ${\textit HR}_1$ and ${\textit HR}_2$ hardness ratios evaluated from the pn data (see the definition of ${\textit HR}_1$ and ${\textit HR}_2$ in the text). Columns 8 to 12 and 13 to 17 summarize the results of the cross-correlation with the USNO (and GSC) and 2MASS catalogues respectively. Columns 8 and 13 yield the numbers of optical and IR counterparts within 8 arcsec from the X-ray source, while Cols. 9 and 14 provide the angular separation for single counterparts.

No hardness ratio could be derived for source #39, since it lies inside the wings of the PSF of the bright central source HD 159 176 (#44).
IR magnitudes between brackets were flagged as uncertain in the 2MASS database because of band filling or diffraction spikes.
