bl2beam
(bl, theta)¶ Computes a circular beam profile b(theta) in real space from its transfer (or window) function b(l) in spherical harmonic space.
Parameters: - bl : array
Window function b(l) of the beam.
- theta : array
Radius at which the beam profile will be computed. Has to be given in radians.
Returns: - beam : array
(Circular) beam profile b(theta).
