Examples of MS-fitting for the −1.3 ⩽ [Fe/H] _CG < −1.1 metallicity group. The reference cluster is NGC 6981 (dashed line). Each cluster MRL (solid line) has been fitted to the reference cluster in the magnitude intervals [( M ^TO _{F606
W} − 2.5) < M _{F606
W} < ( M ^TO _{F606
W} − 1.5)], and [( M ^TO _{F606
W} + 1.5) < M _{F606
W} < ( M ^TO _{F606
W} + 3.0)] (shaded regions).
