\caption{\label{tab:data}Overview of the source spectral analysis for each field. ``Faint'' denotes the number of sources with $<$50~source counts, in brackets is the number of sources for which we cannot quote a luminosity. For details on the HMXB candidates see text. The faint limit is the luminosity below which all sources have less than 50~source counts.}
