SFRs vs stellar masses of the ALPINE [CII]-detected (green squares) and undetected (yellow squares) galaxies. Red symbols represent [CII] nondetections with less precise spectroscopic redshift (see Sect. 2.2). The main-sequence of star-forming galaxies by Speagle et al. (2014) is shown as the black dot-dashed line, with its ±0.3 dex width represented by the gray shaded region. Top and right panels report the distributions in stellar mass and SFR, respectively, for both the detections and nondetections.
