Notes. Columns: (1) Source ID; (2),(3) IDs of the HST-WFC3 (from the CANDELS catalog) and ZFOURGE counterparts of these detections (the cross correlations between ALMA and HST-WFC3 and between ALMA and ZFOURGE are discussed in Sect. 4.4). b indicates HST-WFC3 galaxies located in a radius of 0″6 around the ALMA detection, although strong evidence presented in Sect. 7 suggests they are not the optical counterparts of our detections; (4), (5) RA and Dec of the sources in the ALMA image (J2000); (6), (7) positions of HST-WFC3 H-band counterparts when applicable from Guo et al. (2013), (8), (9) distances between the ALMA and HST source positions before (ΔHST1) and after (ΔHST2) applying the offset correction derived from the comparison with Pan-STARRS and Gaia; (10), (11) offset to be applied to the HST source positions, which includes both the global systematic offset and the local offset; (12) distance from the closest IRAC galaxy.

For AGS15 we used the distance given in the ZFOURGE catalog (see Sect. 7).

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
