Observed and calculated normal color indices and indices in three photometric systems

We estimate the reliability of previously derived normal energy distributions for stars by comparing normal color indices in three photometric systems (W BV R, uvby, and Vilnius) calculated using these distributions with indices derived from photometric observations. Earlier, we used photometric data from W BV R and uvby catalogs to derive normal color indices for these systems not available in the literature, in the form of mean color indices and indices obtained for representative groups of normal, unreddened stars. The results can be used to estimate both the quality of our normal distributions and the reliability of the normal color indices in the three photometric systems considered.
