Example of the detection limits calculated for EBLM J2011-71, which is one of the BEBOP targets with the highest precision. Each line represents the smallest detectable minimum circumbinary planet mass (m_c sin I_c) as a functionof the planet’s period (P_c) for a different orbital phase of the planet. There are 20 orbital phases tested, all equally spaced. The blue square near the top of the plot is the detected circumbinary object in the EBLM J2011-71, which is in fact not a circumbinary planet but rather alow-mass tertiary star.
