Let $\ui\di$ be the Dirac operator on a $D=2d$ dimensional ball $\mcB$ withradius $R$. We calculate the spectral asymmetry $\eta(0,\ui\di)$ for D=2 andD=4, when local chiral bag boundary conditions are imposed. With these boundaryconditions, we also analyze the small-$t$ asymptotics of the heat trace $\Tr (FP e^{-t P^2})$ where $P$ is an operator of Dirac type and $F$ is an auxiliarysmooth smearing function.Comment: 23 page
