[yt-users] reading RAMSES files - missing cosmological_simulation flag?

[Sam Geen]

Yes, sorry, I've been quite distracted recently (moved institute, thesis 
to write, etc). Not sure when I'll have time to look at this properly, 
but hopefully in the next couple of months if you guys still need 
another pair of hands.

As for cosmological simulations, one possible test is that all the units 
are 1.0 in non-cosmological runs (see amr/units.f90 in the ramses 
source). Not sure if there's a more elegant test.
