Modified Rauzy test. The Rauzy completeness statistic (T_c) is shown as a function of the integrated flux. The blue points represent ⟨T_c⟩ from 1000 runs varying the line-of-sight distance of each detection within 3R_vir of the Fornax cluster. The uncertainties are computed as the variance, and the grey lines show each individual test. The short-dashed red and long-dashed black lines represent the 97.7% (T_c = −2) and 99.4% (T_c = −3) confidence intervals, respectively.
