It has been pointed out to the author that in Sect. 6 of this paper, an incorrect mass was used to calculate the predicted mass loss for the cluster NGC 6791. The mass used of 1.6 M referred to the other cluster discussed in Miglio et al. (2012), NGC 6819.

Although the values given in Table 6 of the paper are correct, the inferences drawn from them need to be modified, even though all conclusions remain unchanged.

Table 1 lists the predicted mass loss for an initial mass of 1.2 M (Miglio et al. determined the mass of stars on the RGB of NGC 6719 to be about 1.23 M).

As the mass loss for a lower initial mass is larger on the RGB, the scaling factors η1 and η2 are lower, namely η1 = 7.5    ±    4 and η2 = 9    ±    5.

The factor mentioned in the sentence of the abstract “Using a scaling factor of  ~ 10    ±     ~ 5, both relations can fit this value”. should be  ~ 8    ±     ~ 5.
