galpy.df.streamdf.pangledAngle

streamdf.pangledAngle(angleperp, dangle, smallest=False)

Return the probability of a given perpendicular angle at a given angle along the stream.

Parameters:

• angleperp (numpy.ndarray) – Perpendicular angle.

• dangle (float) – Angle offset along the stream.

• smallest (bool, optional) – Calculate for smallest eigenvalue direction rather than for middle. Default is False.

Returns:

p(angle_perp|dangle)

Return type:

numpy.ndarray
