CROSS CATALOGUE MATCHING WITH VIRTUAL OBSERVATORY AND PARAMETERIZATION OF STARS

Virtual Observatory facilities allow users to make a fast and cor- rect cross-matching of objects from various surveys. They yield multi-color photometry data (color indices) on registered objects and make it possible to determine stellar parameters. A method of catalogue cross-matching, as well as its application to various areas in the sky and preliminary results of stellar parameterization, are discussed in the paper. We also make a critical analysis of modern stellar spectral atlases.
