Query: Angular Dependence of Coherent Pion Production by Neutrinos   Coherent pion production by neutrinos has been interpreted in the framework
of the Partially Conserved Axial Current hypothesis (PCAC) and explicit model
calculations are available. In this article we compute angular correlations for
the produced pions which may help to separate the signal from the background.
We present many figures useful for the experiments and compare them with
another model.
