Spatial distribution of the X-ray sources with radio associations in the main field overplotted on the H i map of Stanimirovic et al. (1999). The colour scale indicates the column density in units of 10²¹ cm^-2. The white line marks the XMM-Newton main field of the SMC survey. Seven additional sources are located in outer fields, not shown here. Labels give the source number (Col. 1 in Table 2). Radio sources in X-ray clusters of galaxies (Table 3) are labelled with C. X-ray radio correlations are shown by circles. If the source shows a jet-like structure in radio, it is shown by a boxed circle. Sources that are classified as galaxies are shown by boxes. Sources that are within ClGs are marked with diamonds. Radio sources with −0.3 < α < 0 are plotted in cyan, others in white.
