Notes. The VLT/MUSE exposure time was 2804 seconds, divided over four exposures. F_X, peak is reported in the 0.3−10 keV energy range and given in units of 10⁻¹³ erg s⁻¹ cm⁻². The positional uncertainty is the square root of the RMS on the astrometric calibration as described in Section 3 plus the 1σ uncertainty of the X-ray position as given in the literature, added quadratically, as described in Section 3 and given at 1σ confidence level. ^( † )Value taken from Quirola-Vásquez et al. (2022). ^( ‡ )This source was detected at a high off-axis angle in the CXO-ACIS instrument. Lin et al. (2022) and Quirola-Vásquez et al. (2022) reported this FXT simultaneously with slightly different RA and Dec due to a combination of the difficulty of performing astrometry on high off-axis sources and a different catalogue used to perform the astrometry. We note that within their respective uncertainties, the coordinates are fully consistent within 2σ. We used the coordinates and uncertainty presented in Lin et al. (2022). ^( * )The RA, Dec and positional uncertainty in the X-ray position for these sources were obtained from the XMM-Newton serendipitous catalogue (Webb et al. 2020).
