Notes. Uncertainties correspond to the 68% confidence level, where these are provided in brackets, they refer to the last significant figures. The instruments used for the observations are indicated by TR – TRAPPIST, Eu – Euler, SP – SPECULOOS, W – WASP, COR – CORALIE spectrograph, HARPS – HARPS spectrograph. Dates refer to BJDUTC − 2 450 000. The detection of the sky-projected rotation velocity is reliable for v sin i1 > 5 km s−1. (*)D denotes the observed eclipse depth of EBLM J0555-57A. A blend of the eclipse by a third component is accounted for in the derivation of the stellar radii, described in von Boetticher et al. (2017). (**) ssuming a negligible inclination of the primary star spin axis. (†)Subtraction of the background flux.
