Abstract:
We develop a method for deriving distances from spectroscopic data and
obtaining full 6D phase-space coordinates for the RAVE survey's second
data release.
Description:
We used stellar models combined with atmospheric properties from RAVE
(effective temperature, surface gravity and metallicity) and (J-Ks)
photometry from archival sources to derive absolute magnitudes. In
combination with apparent magnitudes, sky coordinates, proper motions
from a variety of sources and radial velocities from RAVE, we are able
to derive the full 6D phase-space coordinates for a large sample of
RAVE stars. This method is tested with artificial data, Hipparcos
trigonometric parallaxes and observations of the open cluster M 67.

Note (1): The coordinate system we use is a right-handed Cartesian
coordinate system centred on the Galactic Centre (GC): the x axis
is aligned with the GC-Sun axis with the Sun located at x=-8kpc; the
y axis pointing in the direction of rotation and the z axis pointing
towards the Northern Galactic Pole (NGP).
The velocities with respect to the Sun in the directions of (x, y, z)
are (U, V, W) respectively, with the rest frame taken at the Sun (such
that the Sun is at (U, V, W)=(0, 0, 0)). The catalogue also includes
cylindrical polar coordinates (V{rho}, Vφ , Vz), defined in
a Galactic rest frame such that the local standard of rest (LSR) moves
at vφ=-220km/s. To transform from the rest frame of the Sun to
the Galactic rest frame, we use vLSR=220km/s for the LSR and take the
velocity of the Sun (10.0, 5.25, 7.17)km/s with respect to the LSR
(Dehnen & Binney, 1998MNRAS.298..387D 1998MNRAS.298..387D).
