diskdf.sampleVRVT(R, n=1, nsigma=None, target=True)[source]

NAME:

sampleVRVT

PURPOSE:

sample a radial and azimuthal velocity at R

INPUT:

R - Galactocentric distance (can be Quantity)

n= number of distances to sample

nsigma= number of sigma to rejection-sample on

target= if True, sample using the ‘target’ sigma_R rather than the actual sigma_R (default=True)

OUTPUT:

list of samples

BUGS:

should use the fact that vR and vT separate
