Regular poles for the p-adic group GSp4-II

We compute the regular poles of the L-factors of the admissible and irreducible representations of the group GSp4, which admit a nonsplit Bessel functional and have a Jacquet module length of 3 with respect to the unipotent radical of the Siegel parabolic, over a non-Archimedean local field of odd characteristic. We also compute the L-factors of the generic representations of GSp4.
