Scientific paper

We constrain the properties of the spotted regions on the photosphere of
the active late-type star DX Leonis by comparing the observed amplitudes
of light and color variations with synthetic amplitudes obtained by
means of Dorren's spot model and computed for a grid of values of spot
temperatures, areas and latitudes.
