Table 1: Sample of sources studied in this paper. We give their name, their coordinates (J2000 and galactic), the total galactic column density of neutral hydrogen ( $N_{\rm H}(H {\sc i})$ ) and the total galactic column density of molecular hydrogen ( $N_{\rm H}({\rm H}_{\rm 2})$ ) in the line of sight, the X-ray column density of the source ( $N_{\rm Hx}$ ), their type (SFXT or OBS - obscured sources) and their spectral type (SpT). Their spectral classifications come from optical/NIR spectroscopy, reported in the following references (Ref): c: Chaty et al. (2008), f: Filliatre & Chaty (2004), i: in 't Zand et al. (2006), n1: Negueruela et al. (2005), n2: Negueruela et al. (2006a), n3: Nespoli et al. (2007), p: Pellizza et al. (2006), t: Tomsick et al. (2006).
Table 2: Summary of VISIR observations of newly discovered INTEGRAL sources. We give their MIR fluxes (mJy) in the PAH1 (8.59 $\mu$ m), PAH2 (11.25 $\mu$ m) and Q2 (18.72 $\mu$ m) filters. When we did not detect a source, we give the upper limit. When no flux nor upper limit is given, the source was not observed in the considered filter.
Table 3: List of GLIMPSE counterparts we found for 9 sources. We give their name, their separation from the 2MASS counterparts and their fluxes in mJy.
Table 4: Adopted $\frac{A_\lambda}{A_{\rm v}}$ values.
Table 5: Summary of best-fitting parameters of the SEDs of the sources. We give the total galactic extinctions in magnitudes $A_{H {\sc i}}$ and $A_{\rm H_2}$ , the X-ray extinction of the source in magnitudes $A_{\rm x}$ and then the parameters themselves: the extinction in the optical $A_{\rm v}$ , the temperature $T_\ast$ and the $\frac{{R}_\ast}{{D}_{\ast}}$ ratio of the companion and the temperature and radius $T_{\rm D}$ and ${R}_{{\rm D}}$ (in ${R}_{\ast }$ unit) of the dust component when needed. We also add the reduced $\chi ^2$ we reach for each fit.
Table 6: Ranges of parameters that give acceptable fits (90%-confidence) for each source.
Table 7: Summary of spectral types (SpT) and distances ( ${D}_\ast$ ) derived from our fits for confirmed supergiant stars in our sample. ( $^\ast$ ) sources with an accurate spectral type found in the literature ( $^\dagger$ ) confirmed supergiant stars whose temperature derived from our fits was used to assess their accurate spectral type. References to the determination of the spectral type and/or spectral class of these sources are found in Table 1.
Table 8: Summary of the distances ( ${D}_\ast$ ) derived from our fits for sources with unconfirmed spectral classes.
Table 9: Sample of parameters we used to fit the SEDs of the isolated supergiants. We give their galactic coordinates, their spectral types, the interstellar extinction in magnitudes $A_{\rm i}$ and then the parameters themselves: the extinction in the optical $A_{\rm v}$ , the temperature $T_\ast$ and the $\frac{{R}_\ast}{{D}_{\ast}}$ ratio of the star.
