Notes. General: ‘NA’ and ellipses in this table indicate that the value is not available. (a) TESS Input Catalog (TIC v8.2) (Paegert et al. 2021). (b) Gaia EDR3 (Gaia Collaboration 2021); the uncertainty in Teff listed here is 1.5 times the geometric mean of the upper and lower error bars of teff_gspphot. Magnitude uncertainties listed as 0.00 are ≲0.005. (c) AAVSO Photometric All Sky Survey (APASS) DR9, (Henden et al. 2015), http://vizier.u-strasbg.fr/viz-bin/VizieR?-source=II/336/apass9. (d) 2MASS catalogue (Skrutskie et al. 2006). (e) WISE point source catalogue (Cutri et al. 2013). (f) Bailer-Jones et al. (2021), geometric distances. (g) The Gaia renormalised unit weight error (RUWE) is the square root of the normalised χ2 of the astrometric fit to the along-scan observations. Values in excess of about unity are sometimes taken to be a sign of stellar multiplicity. (h) Abbreviations for astrometric_excess_noise and astrometric_excess_noise_sig (Lindegren et al. 2021; https://gea.esac.esa.int/archive/documentation/GDR2/Gaia_archive/chap_datamodel/sec_dm_main_tables/ssec_dm_gaia_source.html); these are a measure of ‘the disagreement, expressed as an angle, between the observations of a source and the best-fitting standard astrometric model’. Values of astrometric_excess_noise_sig ≳2 are considered significant. (i) Binary and outer orbital periods from this work; given here for reference purposes.
