Abstract: We present a new mapping algorithm, the Accretion Stream Mapping code, which uses the complete emission-line light curve to derive spatially-resolved intensity distributions along the surface of a stream modelled as a duodecadon-shaped tube. We have successfully tested this method on artificial data and then applied it to emission line light curves of H beta, H gamma and He II lambda 4686 from the magnetic CV HU Aqr. We find Balmer emission near the threading point in the stream facing the white dwarf and helium emission all over the magnetic part of the stream.
