Sky positions, in Galactic coordinate projection, of FXT candidates: the initial 151 FXT candidates of this work are represented by blue triangles (see Sect. 2.6; some symbols overlap on the sky); the final sample of eight extragalactic FXT candidates from this work are denoted by large red stars (FXTs 20 and 22 overlap on this scale); and the final sample of 14 extragalactic FXTs analyzed in Paper I are shown as orange circles (FXTs 14 and 16 overlap on this scale). The background gray scale encodes the location and number of distinct colocated or closely located observations among the combined 3899 and 5303 Chandra observations used in this work and Paper I, respectively.
