Comparison between galaxy abundances of four observed clusters taken from Weinmann et al. (2011) (triangles) and the corresponding results obtained with discount method (circles) in mass bins centred in these clusters. Here, we use masses of 6 × 10¹³ M_⊙ for Fornax, 1.7 × 10¹⁴ M_⊙ for Virgo, 6.7 × 10¹⁴ M_⊙ for Perseus and 1.3 × 10¹⁵ M_⊙ for Coma. Top panel show the abundances for M_lim = −16.7 and bottom panel for M_lim = −19.0.
