Distribution of orbital period, eccentricity and (logarithmic) mass functions of LMC and SMC fundamental-mode binary Cepheid candidates (shown at the top, from left to right). The dashed vertical line denotes the median value of the distribution. Distribution of the projected semimajor axes, eccentricities and (logarithmic) mass functions as a function of the orbital periods (bottom, from left to right). Filled blue and red dots denote LMC and SMC fundamental-mode strong candidates respectively. Empty symbols denote the marginal candidates.
