Left panel: Comparison between WD temperatures obtained from individual literature studies versus those of the Gentile Fusillo et al. (2021) WD catalog. Values from the WD catalog that agree within the uncertainties with the literature values are shown in light red. We also show differences between these values of less than 10% (in brown), between 10% and 20% (in green), and more than 20% (in blue). Right panel: Orbital period versus donor mass. Standard evolution track for CVs (Knigge et al. 2011) is shown in pink as a reference.
