Notes.
Using Eqs. (9), (11), and Fig. 2 from Graham & Driver (2005), to pass from μe to ⟨μ⟩e and to mint.
Adopting Mi, ⊙ = 4.57 from http://astroweb.case.edu/ssm/ASTR620/mags.html#solarabsmag
Stellar mass obtained by adopting M/Li, ⊙ = 1.27. This is the mean of the values obtained for the (r − i)0 colour of the bulge from the two relations provided by Roediger & Courteau (2015), fitted from two different sets of theoretical models.
