Fig. 8.


First five panels: CMD of all GES targets (small black dots) of the BVIJH magnitudes as a function of B − V. RC giants are indicated with magenta plus symbols. The black solid line indicates the slope obtained by the fit; the green and blue arrows indicate the reddening vectors corresponding to the standard and abnormal reddening laws, respectively. The lower right panel shows a comparison of the fitted slopes for RV giants in various photometric bands with the literature reddening laws.
