Rebinned local XXL-S RL HERG RLF with M_i <  −22 (blue shaded region) and the corresponding fit (solid blue line). The original local RL HERG RLF with M_i <  −22 is shown as the cyan circles and its fit is the dashed blue line. The rebinning caused an increase in the normalisation of the fit (log[]= − 7.552). However, this did not significantly affect the measurement of the evolution of Ω_kin for RL HERGs given the large uncertainties in the Cavagnolo et al. (2010) scaling relation. For comparison, the Pracy16 HERG RLFs with m_i <  20.5 (including all sources) and M_i <  −23 are shown.
