Query: Compact periods of Eisenstein series of orthogonal groups of rank one   Let G=O(n+3) be an orthogonal group of rank one and H=O(n+2) an anisotropic
subgroup. We unwind the period along H of a spherical Eisenstein series of G
against a cuspform of H into an Euler product and evaluate the local factors at
odd primes.
