Supergalactic frame #53

Open low-sky opened 9 years ago

low-sky commented 9 years ago

@pfederl -- Does ASTlib support a supergalactic reference frame on top of J2000, B1950, Ecliptic etc. It's a supported frame in CASA viewer and we should include it if it's already in ASTlib.

@slovelan -- Do you know if supergalactic is actually used much by the casaviewer community?

I believe the following are supported by AST (copied from AST documentation):

Hi All,

Can you remind me which systems we are currently supporting?

I always get confused between ICRS and FK5.

Sincerely,

No, I'm sorry I don't know how much supergalactic. Perhaps Jeff would know or could refer you to someone who does. Susan

All right, let's go with the following in order

The "NATIVE" uses the system of the file. It may not be the system given here but ASTlib may happily parse it and give grids. Would that work?

I think if someone wants non-standard equinox for FK5 then they can write a plugin!
