Description We present a new method of phenomenological modelling of light curves based on ideas of the principal component analysis that enables a realistic description of light variations of a variable object with a minimum of free parameters. The application of the method is demonstrated on the light curve analysis of magnetic CP stars HD 90044 and HD 125248.
