Notes.
The optical cross-matched tables are built from the VEXAS-AllWISE3 (matching radius of 3″). The spectroscopic table uses SDSS and 6dFGS and it is also matched with VEXAS-AllWISE3. The X-ray table used the 2RX+AllWISE and XMM+AllWISE tables by Salvato et al. (2018) (see Sect. 6 for more details) and the 21 cm table is obtained from SUMSS. In these two cases the match with AllWISE is within a 10″ matching radius, given the poorer resolution of X-ray and 21 cm surveys.
