Table 5

Selection criteria used to remove the results of the binary pipeline that are identified as being of poor quality or unphysical.

Crit.	Short description	Number of rejected objects
1	Binary pipeline solution does not converge	1425

2	ΔV_r < 15 km s⁻¹	3465

3	Luminosity ratio (secondary/primary) in any band < 0.1	1857

4	Mismatch of ΔV_r between CCF and binary pipeline, > 20 km s⁻¹	266

Notes. The numberof rejected objects is evaluated on a sample that was previously cleaned by all criteria listed prior to the one in question.
