Table 2: Spectral and variability analyses of the brightest X-ray sources in the field of NGC 6383. The neutral hydrogen column density was frozen in the spectral fits at the interstellar value ( $1.91 \times 10^{21}$ cm^-2). Columns 2 and 3 list the resulting best fit temperatures of the MEKAL components, whilst column 4 provides the reduced $\chi ^2$ along with the number of degrees of freedom. Columns 5 and 6 yield the observed and absorption corrected fluxes respectively. The quoted uncertainties correspond to formal errors on the spectral fits.
Table 3: X-ray sources with bright optical counterparts that are known from other catalogues than the USNO or GSC. The last column yields the reference for the spectral type (FJL = FitzGerald et al. 1978, vdA = van den Ancker et al. 2000). The photometric data are taken from FJL, except for Thé 7 and 26 for which we adopt results from Eggen (1961).
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.
