The authors discuss the interplay among (super-)coordinate, Weyl and Lorentz anomaly both in chiral and non-chiral supergravity represented by (1,0) and (1,1) two-dimensional models. It is shown that for this purpose two regularization-dependent parameters are needed in the effective action. They discuss in full generality the regularization ambiguities of the induced effective action and recover the corresponding general form of the anomalous Ward identities. Finally, they explain the difference between chiral and non-chiral supergravity models in terms of the free parameters, and establish the relation between these two models by projecting (1,1) into (1,0) supersymmetry.
