Does the fact that two photons are entangled influence the transverse degree of coherence in the signal and/or idler beam?

There were many experiments done with momentum-entangled photon pairs created through SPDC. Works of Strekalov [Phys. Rev. Lett. 74, 3600 (1995)] and Hong [J. Opt. Soc. Am. B 15, 1192 (1998)]...
