Notes. ( † )The radio counterpart to HCG15-D was found to exhibit variability at high frequencies. Flux density measurements from all observational epochs are reported. Notes: we omit HCG15-B here as no radio emission is detected by any of the telescopes involved in this work. For HCG15-A, we note which components are detected: a nuclear point source (PS), plus in some cases extended emission associated with a likely star-forming disk.
