Notes. Columns: (1) source ID; (2), (3) coordinates of the detections in the ALMA image (J2000); (4), (5) positions of HST-WFC3 H-band counterparts when applicable from Guo et al. (2013), (6), (7) distances between the ALMA and HST source positions before (ΔHST1) and after (ΔHST2) applying both the systematic and local offset correction presented in Sect. 3; (8), (9) offset to be applied to the HST source positions, which includes both the global systematic offset and the local offset; (10) distance from the closest IRAC galaxy; (11) IRAC random association (RaA) between the ALMA detection and the closest IRAC galaxy.
