Mass distribution of our RR sample. Top: as a histogram. The hatched bars show the distribution for only clusters which also host a RH. PSZ2 G069.39+68.05 and PSZ2 G107.10+65.32 are both excluded. Bottom: relic power vs. cluster mass with redshift on the colour bar. Triangles denote candidate relics and plusses those relics which are part of a double relic pair. All other relics are plotted as circles. Red circles surround relics in clusters which also host a RH. PSZ2 G069.39+68.05 and PSZ2 G107.10+65.32 are labelled, with the labels above and right of the data points.
