Scientific paper

The paper is dedicated to the problem of the estimation of the orbital and physical parameters of the short-period W UMa-type system SW Lacertae on the basis of the light-curve analysis. The analysis shows that the system's components are in an overcontact configuration. The Roche model (with two dark spot regions on the components) gives a good fit to the observations. The basic parameters of the system and of active spot regions are estimated with both hypotheses.
