The details on how the beams were derived is presented in Makiwa et al., 2013, Applied Optics, 52, 3864.
The beam maps FITS files *beam-map* are 3-D images (cubes) with dimensions [257,257,74] for SLW and [257,257,83] for SSW. The third axis is the frequency in GHz. The FITS file 'image' extension contains the cubes.
The beam FWHM and solid angles are provided in coma-separated-value tables fwhm_omega* for both bands (SSW and SLW) and for the two spectral resolutions: HR and LR. The HR and LR versions have different frequency grids.
