Abstract
We built autocorrelation functions of the light curves in the microlensing model of a remote source by a stochastic system of point masses (stars) and extended configurations – putative dark matter (DM) clumps. Besides isolated DM clumps we consider superpositions of point masses and clumps with the same center. The autocorrelation functions are generated for several sets of parameters that characterize the relativeconcentration of point and extended masses and an external shear.

Keywords
Extragalactic gravitational lensing, dark matter
