Notes. This list was compiled from Muñoz-Giraldo et al. (2024a) and Muñoz-Giraldo et al. (2024b). We include the confirmation of a late-type donor in the system through spectroscopy (S) or photometry (P) for 21 confirmed period-bouncers (referred to as bona fide period-bouncers). The remaining 12 confirmed period-bouncers do not yet have a detected late-type donor. The score value of each system is given for: the period-bounce scorecard defined by Muñoz-Giraldo et al. (2024a) and the reduced period-bounce scorecard (see Sect. 2.2). The probability of being a WD (PWD) is presented for the period-bouncers found in Gentile Fusillo et al. (2021). We indicate the period-bouncers with an eROSITA detection from the western (x) and eastern (-) Galactic half-sky.
