Jellyfish galaxy fraction (relative to all star-forming LoTSS sources) as a function of group or cluster halo mass. Purple triangles show the jellyfish galaxies in groups identified in this work and the red star shows the cluster jellyfish galaxies from R21b. Vertical error bars are 68% binomial confidence intervals from Cameron (2011) and horizontal error bars show the width of each halo mass bin. The horizontal line shows the fraction of LoTSS sources in the field sample that passed our jellyfish galaxy criteria (see Sect. 2.3), along with the 90% confidence region (shaded band).
