heal.abstract	This paper presents an accuracy analysis of the Method of Auxiliary Sources (MAS), for transverse electric (TE) scattering from a metallic, circular cylinder. An analytical inversion of the matrix is facilitated via exact eigenvalue computation and subsequent diagonalization. This property leads to the derivation of analytical expressions for the discretization error and the condition number, and also to an asymptotic estimate for the latter, revealing an exponential growth with the scatterer size. The optimal location of the auxiliary sources is investigated, on the basis of error minimization, thus resolving the most challenging issue concerning the MAS efficiency, and enhancing the method's computational robustness.	en
