Notes. Sources positions, flux densities and sizes are listed. Where the sources are small and compact major and minor axis measurements and flux densities are taken from Gaussian fitting of the source. Where the source structure is more extended, largest angular sizes (LAS) are included and the flux densities as measured from SEAC (see Sect. 2.2). Where extended sources contain knots of emission, Gaussian fitting has been performed on the individual knots in addition to the whole source. For the relevant sources these are referred as A-D. Source type descriptions are as follows: Isolated sources show bright emission clearly isolated from other features and represent the most likely candidates for potential emission associated with stellar sources. Isolated/diffuse sources are similar to the isolated sources but are in the presence of low surface brightness emission. These could therefore represent stellar emission or brighter knots in diffuse background emission. Extended/diffuse represent sources that appear to be extended background emission.
