Notes. For screening catalogues, the columns ‘Screening’ and ‘Flags’ indicate which catalogue entries we used for screening and flagging, respectively. Catalogues that have ‘-’ listed in one of the two selection columns were not used for the corresponding task. If ‘None’ is listed, the entire catalogue is used. Screening catalogues without footnote annotations are catalogues of background AGNs. (a)Tycho catalogue of bright foreground stars. (b)Australian Square Kilometre Array Pathfinder (ASKAP) 888 MHz radio continuum survey of the LMC. (c)Heraklion Extragalactic Catalogue (HECATE) of galaxies. ZHT04: Zaritsky et al.
