NAME:
calc_stream_lb
PURPOSE:
convert the stream track to observational coordinates and store
INPUT:
Coordinate transformation inputs (all default to the instance-wide values):
Vnorm= circular velocity to normalize velocities with
Rnorm= Galactocentric radius to normalize positions with
R0= Galactocentric radius of the Sun (kpc)
Zsun= Sun’s height above the plane (kpc)
vsun= Sun’s motion in cylindrical coordinates (vR positive away from center)
OUTPUT:
(none)
