Distribution of the 584 candidate hot subluminous stars within 500 pc (blue) for three astrometric quality control parameters provided by Gaia DR3. Top panel: AEN vs RUWE where all currently known hot subdwarf composite and non-composite binaries are given as magenta and black circles, respectively. The dashed grey horizontal and vertical lines indicate an AEN of 1.0 and a RUWE of 1.4, respectively. The red dashed line and the corresponding red shaded area represent the rejected sources in the sample. Bottom panel: same as top, but with par-allax_over_error vs RUWE.
