Table 3: Atmospheric parameters for B-type stars in NGC 3293 and NGC 4755 as derived from non-LTE TLUSTY model atmospheres. The majority of the data comes from FEROS however those taken with FLAMES are marked with1. Identifications and spectral classifications are taken from Paper I. Both the initial and corrected atmospheric parameters are shown following the discussion in Sect. 4. The uncertainties in these parameters are typically 1000 K for $T_{\rm eff}$, 0.20 dex for $\log {g}$, 3-5 km s-1 for $\xi $ and 5 km s-1 for $v \sin i$.
