Fig. 2
B−RC vs. RC color−magnitude diagram with our seven spectral classes. The black solid line is the color−magnitude relation, (B−RC)diff = 0. The blue dashed line indicates the (B−RC)diff = −0.5 value which we use to separate HDSr and HDSb following M04. The two red dashed lines indicate the locus of the red sequence galaxies, | (B−RC)diff | < 0.3.
