Abstract
We present a new mapping algorithm, the Accretion Stream Mapping, which uses the complete emission-line light curve to derive spatially resolved intensity distributions along the stream on a surface created as a duodecadon shaped tube. We successfully test this method on artificial data and then applied it to emission line light curves in Hbeta, Hgamma and HeII 4686 of 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.
