Abstract

We present results from a preliminary analysis of a 15 GHz VLA + Pie Town data set of B0218+357 which shows a wealth of structure in the Einstein ring of this system. From these data we obtain constraints for the position of the lensing galaxy, which will potentially improve the accuracy in the determination of H0, and maps of the lens plane and the unlensed source plane. This includes the first LensClean reconstruction of the polarization structure of the source plane.

(Posters of this conference will not be published in the proceedings.)
