Slopes for the line models fitted to the data in Fig. 5.

Group m (Total) m (RC) m (Dwarfs)

Cyan 0.27 ± 0.064 0.27 ± 0.059 0.88 ± 1.147
Brown 0.21 ± 0.014 0.25 ± 0.020 0.16 ± 0.022
Green 0.28 ± 0.020 0.23 ± 0.110 0.25 ± 0.019
Blue 0.23 ± 0.054 0.06 ± 0.115 0.29 ± 0.095
Red 0.05 ± 0.018 0.09 ± 0.035 0.17 ± 0.032

Notes. The slope is estimated using the Theil-Sen estimator from the complete dataset (Col. 2), the RC stars alone (Col. 3), and dwarfs (Col. 4). Reported errors are estimated by bootstrapping.
