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).
