Modern astronomical surveys for parameterization of stars and interstellar medium

Abstract

Developing methods for analyzing and extracting information from modern sky surveys is a challenging task in astrophysical studies and is important for many investigations of galactic and extragalactic objects. We have designed a method for determination of stellar parameters and interstellar extinctions from multicolor photometry. This method was applied to objects drawn from modern large photometric surveys. In this work, we give a review of the surveys and discuss problems of cross-identification, paying particular attention to the information flags contained in the surveys. Also we have determined new statistical relations to estimate the stellar atmospheric parameters using MK spectral classification.
