Equivalent width and column density from the blind sample compared with results from the literature (Anand et al. 2021; Mishra & Muzahid 2022). The left panel displays the detection in the blind sample as a function of projected distance (in units of R₅₀₀), with the detection in our blind stack depicted as a red circle. In the right panel, we plot the mean of the two points of Anand et al. (2021) and the point of Mishra & Muzahid (2022) closest to our results in projected distance space (see left panel). This second figure highlights the difference in mass range between the samples.
