# 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).
