Tracks of the SSPs of the CBe base in the log(M/L_r)−(g − r) plane. The library contains 6 metallicities and 41 ages. The tracks increase their line width with age (the older the age, the thicker the line). Four signposts mark the position and value of the (logarithmic) age in the lowest metallicity track. The highest metallicity track reddened by A_V = 2 mag together with a reddening vector of this amount are also shown. The density distribution of our sample is underlaid in gray contours encompassing 95% of the points.
