Histogram of the smallest detectable planet mass for the 47 eclipsing binaries in the BEBOP survey. The navy blue solid line calculates the minimum across all possible circumbinary periods and phases. The red dashed line calculates across all possible phases but has a fixed orbital period of 2 yr. We note that one target, EBLM J0500-46, is excluded in the histogram for P_p = 2 yr because its observing timespan is too short to be sensitive to planets at this period.
