And of course a link to basic information
about spectral classes and types:
http://lheawww.gsfc.nasa.gov/users/allen/spectral_classification.html
I should have put this in first but, hey, there you go.
You can actually get XYZ Gliese data online too, if
you go looking, so you can plot absolutely huge XYZ
starmaps if you want. The problem I find is that you
need to "correct" because any Earth-centered data will
be very heavy on brighter stars the farther you go
out--a star the size of A Centaurus C (Proxima) would
be virtually unfindable if it were 100 or so light
years out instead of 3.9.
(I also add in brown dwarfs [Spectral Class L] and very
small red stars [M5-M8] to my maps, because though we
can't see them, they've been shown to exist.)
