The area covered by the combined fields is $\\rm 9.5\\times10^{-4}deg^2$ at 1.1mm and $\\rm 6.6\\times10^{-4}deg^{2}$ at 1.3mm. We improved the source extraction method by requiring that the dimension of the detected sources be consistent with the beam size. This method enabled us to remove spurious detections that have plagued the purity of the catalogues in previous studies.
