I took the spectra from the online data published by Schiavon, not from
the website.

In the above results I have a preferences for the results found with
MILES, since the residuals are smaller. Its the only objective thing I
could figure out.
Note that the pops in MILES are solar-scaled pops, so I have no
constraint on the abundance ratios.
