Notes. Dust disks, white-dwarf-main sequence or M dwarf are confirmed by Spitzer observations, and the white-dwarf-brown-dwarf pairs do not have Spitzer observations, so we list the discovery paper. Steele et al. (2013) confirmed the infrared excess spectroscopically using radial velocity measurements and Wilson et al. (2019) suggested it is not a dust disk because the white dwarf’s atmosphere is not polluted. IR excess EDR3 is the assessment of the infrared excess made on this paper: N means there is no CatWISE photometry; empty entry means the source has been lost in one of the steps of our criteria. We show the reference where the Spitzer observations are reported. We show, for reference, the first three lines of 107 in total.
