WMAP DR1 Beam Radial Profiles Description
The data made available through this page has been updated. The most recent version of this data may be accessed through https://lambda.gsfc.nasa.gov/product/wmap/current/
For each differencing assembly, a symmetrized radial beam profile is computed by fitting the ensemble of individual A- and B-side Jupiter observations with Hermite polynomials of even order.
The polynomial fits to the data are tabulated in 0.5 arcminute increments, increasing outwards from beam center (radius=0.0) to the cutoff radius chosen for the window function determination. The profiles are normalized to 1.0 at r=0.
