Figures for 2M21442066+4211363, with ﹩{ \mathcal L }=79 \% ﹩ at P = 3.30 days. (Top) Lomb–Scargle periodogram power as a function of period (black) and the histogram of MCMC samples obtained during the period search (red). (Left) Corner plot of the posterior probability distribution given by the random walk. (Bottom right) RV plot of this system. The solid blue curve is the primary component velocity, and the red dashed curve is the secondary component velocity. Primary component velocities are marked as squares, and secondary velocities are marked as circles.
