Notes. Errors are at the 90% confidence level. ( † )The types of sources are symbiotic stars (SS), Galactic M dwarfs (MD), and other types of foreground star (FG). ( * )Flux and luminosity of all sources are calculated in the energy range of 0.2–5.0 keV, except sources No. 1 and No. 8, which are in the energy range of 0.2–10 keV. ( ⋆ )Source No. 5 is the super-soft symbiotic white dwarf system Draco C1. The fitted parameters for this source are taken from Saeedi et al. (2018).
