Notes. Column 1: shorthand identifier (FXT #) used throughout this work. Column 2: X-ray transient identifier (XRT date), plus previous name when available. Columns 3–5: Chandra observation ID, exposure time in units of ks, and date. Column 6: T₉₀ duration, which measures the time over which the source emits the central 90% (i.e., from 5% to 95%) of its total measured counts, in units of ks. Columns 7 and 8: Right Ascension and Declination in J2000 equatorial coordinates. Column 9: off-axis angle of the FXT candidates, with respect to the Chandra aimpoint, in units of arcminutes. Column 10: estimated 2σ X-ray positional uncertainty, in units of arcseconds (see Sect. 2.5). Column 11: hardness ratio (HR) and 1σ uncertainty, defined as HR = (H − S)/(H + S) where H = 2 − 7 keV and S = 0.5 − 2 keV energy bands, using the Bayesian estimation of Park et al. (2006). Column 12: approximate signal-to-noise ratio (S/N). ^( † )Previously reported as FXTs by Xue et al. (2019) for FXT 16, Lin et al. (2019) for FXT 19, and Lin et al. (2021) in the case of FXT 22.
