RAS is the setup used by Jorgensen, Helgaker, Olsen, et al. It's
definitely in Dalton (as it's their program), but I don't know if it's in
any other programs.
In terms of a textbook, you should look at their _Molecular
Electronic-Structure Theory_ book published by Wiley. I don't have a paper
off the top of my head.
RAS1: lower limit on the # of electrons in these orbitals
RAS3: upper limit on the # of electrons in these orbitals
Beyond that, I guess it depends on what sorts of things you're trying to
