Difference between the slope of the rMGMS of each galaxy measured with the fiducial approach and the slope measured when non-detections are excluded, as a function of the mean detection fraction of the molecular gas tracer in each galaxy (μ_DFCO). All values are positive in the y-axis because excluding non-detections always leads to a flatter relation. The PCC of the correlation is indicated in the top-right corner of the panel.
