Abstract
\n \nA light curve modelling and fitting program is presented for\ncataclysmic variable stars and related objects. It allows modelling\nof a three-dimensional disk in conjunction with the Roche-lobe \nfilling secondary star, thus rendering it a very general tool \nfor light curve analysis. \nOptimization of the solution is based on the maximum-entropy\nalgorithm. Some bench-mark tests are presented, and the general\napplicability of the program is explored.\nThe program is used here to study the problem of reconstructing \nthe brightness distribution on flaring accretion disks from \neclipse light curves, and the results are compared with those \nobtained using the well-established standard technique of \nflat-disk eclipse mapping.\nA previous study suggested that erroneous radial temperature\nprofiles were obtained with flat-disk eclipse mapping.\nIt is shown here that flat-disk eclipse mapping does reproduce \nthe radial brightness structure of flared accretion disks\nvery well, provided that the inner disk is not obscured by the outer \nrim of the disk.\n\n\n
