Abstract (from CDS):

A method for determining the time delays in gravitationally lensed quasars is proposed. This method offers a simple and transparent procedure to mitigate the effects of microlensing. It is based on the fundamental properties of representation of quadratically integrable functions by their expansions in orthogonal polynomials series. The method was tested on the artificial light curves simulated for the Time Delay Challenge campaign (TDC0). The new estimates of the time delays in the gravitationally lensed quasars HE 0435-1223 and PG 1115+080 are obtained and compared with the results reported earlier by other authors.
