healpy.sphtfunc.bl2beam

healpy.sphtfunc.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:

blarray

Window function b(l) of the beam.

thetaarray

Radius at which the beam profile will be computed. Has to be given in radians.

Returns:

beamarray

(Circular) beam profile b(theta).
