Using Heterogeneous Data of Multi Frequency Astronomy for Testing Physical Models of GRB Emission

We discuss the problem of data heterogeneity in the search and analysis of inhomogeneities in the light curves of gamma-ray bursts afterglow. We use well-sampled optical and X-ray light curves to find and identify deviations (inhomogeneities) from smooth power law decay of the light curve. We show, in particular that the duration of the inhomogeneities correlates with their peak time (relative to gamma-ray burst trigger) and the correlation is the same for all types of inhomogeneities. The study of inhomogeneities can give us the opportunity to understand the physics of the "central machine" of gamma-ray bursts, which is still far from understanding.
