Relative flux variation of LHS 6343 A vs. the mean anomaly M of the orbit, binned in 40 equal intervals. The Doppler-beaming plus ellipsoidal effect model for our best-fitting parameters is plotted with a solid line (cf. the text). The value of M/2π corresponding to mid-eclipse is marked with a dotted vertical segment, while a horizontal dotted line is plotted to indicate the zero-flux level.
