Variation of the FIRC at 150 MHz with stellar mass for our mass sample. The blue points are upper limits of radio luminosity (lower limit on q) and the black points are for direct detections. The orange points are the median q_TIR measured using survival analysis in each stellar mass bin and the orange line is the linear fit to those points. The light blue crosses are the median q_TIR within each bin measured using the method described in Smith et al. (2021), while the yellow points are the median q_TIRs measured with stacking. The red lines are the linear fit from Eq. (6) of Delvecchio et al. (2021) at the median redshift of our sample converted to 150 MHz with three spectral indices (see legend).
