Number of sources cross-matched between the ALMA 3.5σ detection and the ZFOURGE (Straatman et al. 2016), S-CANDELS (Ashby et al. 2015) and GOODS-VLA (PI: W.Rujopakarn, priv. comm.) catalogs in the image (left panel) and in the negative image (right panel), within a radius of 060 for the ZFOURGE and the VLA catalogs and 070 for the S-CANDELS catalog. Beforehand, we previously removed from the image the sources that had been detected in F18. For example, in the “direct” image, among the 29 source detected both with ALMA at 3.5σ and in the Spitzer/IRAC channel 1 image, 24 are also detected in the ultra-deep K_s image, and 13 are detected with the VLA.
