    VELFRAME

Purpose

---

    Converts radial velocities between Local Standard of Rest, Heliocentric and Galactocentric velocity frames.

Category

---

    Astro

Calling Sequence

---

    Result = VELFRAME(Coords)

Inputs

---

    Coords: 2-element vector of coordinates at which transformation is computed. Assumed
              to be decimal RA and Dec degrees unless /GALACTIC is specified.

Keyword Parameters

---

    GALACTIC: Input coordinates are in galactic coordinates rather than RA and Dec.
    VLSR: Input velocity in LSR frame.
    VHELIO: Input velocity in heliocentric frame.
    VGSR: Input velocity in Galactic standard of rest frame.
    FRAME: Output frame. One of 'LSR', 'HELIO' or 'GSR'.

Outputs

---

    Output radial velocity in desired frame, assuming no proper motion.
