Fraction of cluster Cepheids p_CC(m_Ceph) as a function of the Cepheid mass m_Ceph for Cepheids originating from clusters at different galactocentric radius R_g (indicated by symbols) and of different metallicity Z (indicated by colour). The plot represents Cepheids originating from the whole population of star clusters of the ECMF of Eq. (3). Cepheids of higher mass have a slightly higher probability of being found in clusters.
