Notes. All angular offsets are stated relative to the LABOCA centroid (RA 06:58:37.62; Dec  −55:57:04.8).

(+)

The first uncertainties come from the Gaussian fit and the second uncertainties are the pointing uncertainties.

(*)

We compared the astrometry of the CO(1–0) map to that of the HST image by measuring the position of the elliptical galaxy located 21′′ south of SMM J0658. They agree within 1′′.

(**)

The positions were taken from Gonzalez et al. (2009) who don’t quote any uncertainties.
