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.
Mass lost on the RGB for a 1.2 M⊙ star.
MG would like to thank Dr. Andrea Miglio for pointing out this mistake.
