Notes. ^(a)Column 9 in Table 6. For objects dominated by free-free emission the values are taken as an upper limit. ^(b)Upper limit determined by half of the beam major axis of the Band 7 images (Table B.2). ^(c)From Table 1. ^(d)For the serendipitous detections the M17 age from Stoop et al. (2024) is used.
