Add legacy inertial frames

Open MicheleCeresoli opened this issue 2 years ago • 2 comments

Add the following legacy inertial frames that are built-in in SPICE N067:

  • [ ] B1950
  • [ ] FK4
  • [ ] GALACTIC
  • [ ] ECLIPB1950

See SPICE chgirf.f for details on these axes definitions.

These frames have been inserted and tested, closing.

More detailed and accurate implementations of the FK4/FK5/Galactic frames are needed. See Lieske (1976, 1979) and Standish (1989) and Murray (1989).

@MicheleCeresoli I believe we can close this. Those frames could be implemented by the users independently if needed.
