Souce 1D classification.

CLASS	Description	Number^(a)
STAR	Confirmed Milky Way objects that have parallax and/or proper motion detection (>3σ) from Gaia data.	27(1)
XAGN1	Spectroscopically confirmed broad-line AGNs that have one or more permitted emission line(s) with FWHM > 1000 km s⁻¹.	57(1)
XAGN	Extragalactic sources with spectroscopic redshift measurements without apparent broad line(s) that have either $L_{0.5 - 7 k e V} > 10^{42.5} h_{70}^{- 2} (e r g s^{- 1})$ $\[L_{0.5-7 ~\mathrm{keV}}>10^{42.5} h_{70}^{-2}\left(\mathrm{erg} ~\mathrm{s}^{-1}\right)\]$ , line ratios in the AGN regime in the BPT diagnostic diagram (Baldwin et al. 1981) and/or high excitation lines indicative of an AGN.	65(2)
XAGN*	Extragalactic sources that meet the X-ray luminosity criterion for ‘XAGN’ based on the photometric redshifts.	66(2)
XGAL	Extragalactic sources that do not fall into XAGN1/XAGN category based on the spectroscopic redshifts.	10(0)
XGAL*	Extragalactic sources that do not fall into the XAGN* based on the photometric redshifts.	5(0)
(...)	All others	173(14)

Notes. ^(a)The number includes sub-threshold ID’s (LR < LR_th). The number of the sub-threshold ID’s is shown in the parenthesis.
