Notes. The radio source names, their source diameters, and their fluxes were taken from Table 5 of Fenech et al. (2010). NameR follows the naming convention of Kronberg et al. (1985) with the J1950 coordinates. The source diameters are corrected for our adopted distance of M 82. The source flux density, F1.7, is the total flux density at 1.7 GHz in units of mJy, with the uncertainty in parentheses.
() The radio counterpart of Xp12 was not observed by Fenech et al. (2010) as the SN explosion (SN2008iz) occurred after their observation. The quoted values are flux density at 1.6 GHz measured by VLBI and the diameter measured in August 2010, 1000 days after the explosion (Kimani et al. 2016, the diameter was derived from their R50).
