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.
