Comparative analysis of modern empirical spectrophotometric atlases with multicolor photometric catalogues
Abstract
We present the results of the comparative analysis of the most known semi-empirical and empirical spectral atlases that was carried out using the data from the WBVR photometric catalogue. The results show that standard error of synthesized stellar magnitudes calculated with SEDs from best spectral atlases reaches 0.02 mag. It has been also found out that some of modern spectral atlases are burdened with significant systematic errors. The agreement for the 5000-10000 A spectral range is rather satisfactory, while there are problems for wavelengths shorter than 4400 A.
