streamdf.sample(n, returnaAdt=False, returndt=False, interp=None, xy=False, lb=False)[source]

NAME:

sample

PURPOSE:

sample from the DF

INPUT:

n - number of points to return

returnaAdt= (False) if True, return (Omega,angle,dt)

returndT= (False) if True, also return the time since the star was stripped

interp= (object-wide default) use interpolation of the stream track

xy= (False) if True, return Galactocentric rectangular coordinates

lb= (False) if True, return Galactic l,b,d,vlos,pmll,pmbb coordinates

OUTPUT:

(R,vR,vT,z,vz,phi) of points on the stream in 6,N array
