Caption: Figure 11.
CMD and color–color diagram of eROSITA-selected Galactic targets. The CMD is based on Gaia magnitudes and distances from C. A. L. Bailer-Jones et al. (2021). The CMD shows the X-ray-to-optical flux ratio vs. the Gaia color. Shown in red are likely coronal emitters; shown in blue are likely accreting compact white dwarf binaries. Background objects in the left panel shown in gray are UV-excess objects, candidates for optically selected compact white dwarf binaries.
