The evolution of the luminosity-mass relation with redshift for cluster (left) and field (right) galaxies. Colors and symbols as in Fig. 17. The numbers give the average redshift in each bin. The full lines show the best-fit relation L_B = L_c(M/M_C)^0.75, and the dotted lines L = L_c(M/M_C)^0.5, both relations having uniform galaxy weighting. The dashed lines show the 0.75 power law with selection weighting. The blue lines show the reference line at zero redshifts. The vertical line indicates the M_C = 2 × 10¹¹   M_⊙ mass.
