Comparison of our results in the L_SF − L_AGN plane to other studies. for our sample is scaled by a factor six to estimate the bolometric luminosity. Black circles indicate sources detected with ALMA. Black downward pointing arrows indicate sources detected in ALMA where the sub-mm flux is consistent with being dominated by synchrotron emission. Purple downward pointing arrows indicate sources not detected with ALMA. The X-ray selected sources from Netzer et al. (2016) detected with Herschel over the redshift range z = 2 − 3.5 are indicated with green squares; the large open green square is the SFR of the undetected sources which were stacked to estimate their median SFR. Blue triangles indicate X-ray selected sources from Stanley et al. (2015) over the redshift range, 1.8 <  z <  2.1. The red line is the fit from Rosario et al. (2012) to the mean relation for AGNs over the redshift range 1.5 <  z <  2.5 scaled up by a factor of two (see Netzer et al. 2016, for details). We indicate when the luminosity due to star formation equals that of the AGN with a black solid line.
