streamdf.calc_stream_lb(vo=None, ro=None, R0=None, Zsun=None, vsun=None)[source]

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):

vo= circular velocity to normalize velocities with

ro= 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)
