Notes.
The flux density is obtained by fitting a beam-sized Gaussian to the LABOCA source, while the uncertainty is measured in the jack-knife maps, as discussed in the text.
By construction, the deboosted flux densities have asymmetric uncertainty intervals, but the difference between the upper and lower uncertainties is smaller than the number of significant digits reported here.
Signal-to-noise ratio of each detection calculated from the observed values in Col. 2. This value may be smaller than the threshold for source extraction (3.5σ) which is imposed in the signal-to-noise map.
Sources for which the posterior flux distribution from the flux deboosting algorithm has no local maximum at S > 0 mJy. SMM J161541.2-060817 is very close to the detection threshold, and it is possible that it is not a real source. It was excluded from the number counts calculation. SMM J065915.6-560108 was discussed in Johansson et al. (2010) and has both AzTEC 1.1 mm and Herschel SPIRE counterparts. See also the discussion about spurious detections in Sect. 3.4.
Our derived magnification for this highly magnified source is μ ~ 41, which is different from the value of 75 which was derived from more detailed modelling by Gonzalez et al. (2009), and thus we adopt their value.
