The Encircled Energy Fractions (EEF) for the SPIRE photometer beams are available as an ancillary data product (ADP) in the SPIRE Photometer PSFs folder of the Herschel Legacy Area: http://archives.esac.esa.int/hsa/legacy/ADP/PSF/SPIRE/SPIRE-P/SPIRE-P-EEF.csv Note that the EEFs are calculated assuming a source with a power-law spectrum with index -1, i.e. Fnu ~ nu^{-1}.
