A numerical code is described for constructing Doppler maps from the orbital variation of line profiles of (mass transfering) binaries. It uses an algorithm related to Richardson-Lucy iteration, and is much faster than the standard algorithm used for ME problems. The method has been tested on data of cataclysmic variables (including WZ Sge and SS Cyg), producing maps of up to 300X300 points. It includes an IDL-based set of routines for manipulating and plotting the input and output data, and can be downloaded from http://www.mpa-garching.mpg.de/~henk
