Beam Window Functions
- 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:
- The beam window function
