	eFEDS	eRASS1
Parent sample	21 952	24 375
Non-BAL	21 947	24 315
Non-RL	21 554	21 560
Host contamination ^(a)	17 657	18 921
X-ray selection ^(b)	6947	5542
Optical selection ^(c)	4859	5167

^(a)

Notes.All sources with z < 0.48 are excluded.

^(b)

For the eFEDS sample, NHclass = 2 and S/N > 1 in the soft band; for the eRASS1 sample, there are the usual photon index criteria: Γ_X > 1.7 and Γ_X < 2.8.

^(c)

|Γ₂ − 0.4|> 1.1 for both samples.
