Sequence of quality cuts applied to the 2RXS and XMMSL1 samples to produce the subsample used for spectral analysis. The starting points (2RXS-AllWISE and XMMSL1-AllWISE) are the full samples of 2RXS and XMMSL1 selected sources with AllWISE IR counterparts in the BOSS footprint (see Sect. 2.3). The steps in grey are those that have been discussed in Dwelly et al. (2017).
