[Matplotlib-users] IDL Font question

Hi,
Some colleagues have sent some plots which they generated using IDL
(boo!!! hiss!! :D), and they look quite dissimilar to my matplotlib
ones. I would like to mimic their layout as much as possible, which so
far is a success. The only problem is that I don't know what font to
use. In IDL, I believe it is called "Roman" (there's an smudged
example here: <http://www.astro.ufl.edu/~warner/IDL5220/HW4w.jpg>).
Does anyone know a suitable alternative?

Thanks!
Jose
