# Beam Window Functions

Beam window functions have computed with the Febecop Pipeline (as described here), and
the QuickPol pipeline
(see ^{[1]}).

- QuickPol effective beam window functions

The beam window functions relate, over the full sky, or over a masked sky, the measured angular power spectrum (in the absence of noise) by a set of detectors, to the true underlying sky angular power spectrum (assumed to have isotropic statistical properties, as is the case for the CMB).

They are available in two forms:

- a
- b
