Luminous (baryonic) masses of dwarf spheroidal galaxies?

A recent post by Andrew Yee, titled "Scientists elucidate the origin
of the darkest galaxies in the universe", says that a group led by
Kazantzidis shows that dwarf spheroidal galaxies (dSph's) tend
to be strongly dominated by dark matter and to have very little
ordinary luminous matter (stars and gas) left over, apparently after
eons of ram shock and tidal interactions with very large galaxies.

I can't find any websites having clear information on their actual
luminous masses in (say) units of solar mass.

Can anyone refer me to a site with such actual data, showing estimates
of dSph ordinary masses, as opposed to their apparent
dark matter?

This will help me to know just how high I should raise my eyebrows in
digesting Yee's post.

thanks,

Here's a relevant press release:
http://www.ing.iac.es/PR/newsletter/news7/science1.html
It says the Draco dwarf galaxy has a luminosity of 2e5 solar
luminosities, so if it was composed of sun-like stars, it would have a
mass of 2e5 solar masses. However, the dynamical mass estimate the
researchers get is something like 8e7 solar masses, and hence a mass-
to-light ratio of about 100.

This release has lots of links to the original literature, so you can
check everything for yourself before you raise your eyebrows ;-)
