beam2bl
(beam, theta, lmax)¶ Computes a transfer (or window) function b(l) in spherical harmonic space from its circular beam profile b(theta) in real space.
- Parameters
- beamarray
Circular beam profile b(theta).
- thetaarray
Radius at which the beam profile is given. Has to be given in radians with same size as beam.
- lmaxinteger
Maximum multipole moment at which to compute b(l).
- Returns
- blarray
Beam window function b(l).
