Galactic sky distribution of sources classified from maximum probabilities as quasars (top row) and galaxies (bottom row) by Combmod and Combmod-α using the global prior at HEALpixel level 7 in Mollweide projection. (a) Quasar candidates identified by Combmod-α (1 719 638 sources). (b) Quasar candidates identified only by Combmod (1 230 071 sources). (c) Galaxy candidates identified by Combmod-α (2971 433 sources). (d) Galaxy candidates identified only by Combmod (459 835 sources). The LMC and SMC regions are masked in grey.
