Distance from Bailer-Jones et al. (2021) versus bolometric X-ray luminosity showing the position of the 46 systems in our literature catalog detected in eRASS:3 with respect to the average eRASS:3 sensitivity limit marked by the red line. We show in black the population of CV candidates found in eRASS:3, and in grey a subsample of 775 CV candidates of them that we have selected as period-bounce candidates.
