  Let F be a global field, G an unramified quasi-split reductive group over F
and chi an everywhere unramified automorphic character of a maximal maximally
split torus of G. Using Langlands-Shahidi theory, we compute the meromorphic
function defined by the action of a global standard intertwining operator
associated to chi on a spherical vector and show that the ratio of its poles in
the positive Weyl chamber is well behaved.
