Ratio of the radio luminosity at 150 MHz to the SFR as a function of M_⋆ of SFGs plus RQ AGN for four redshift bins. The points are the modes of the distributions of log(SFR/L_150 MHz). The error bars are the interquartile errors. The straight lines show, for comparison, the relations derived by Smith et al. (2021) for 4 values of the SFR. Although these relations are steeper than ours, the agreement is good for SFGs with typical properties, i.e. where we have more data, both globally and for each redshift bin (see text).
