Classification of population II stars in the Vilnius photometric system. I. Methods.


Abstract (from CDS):

The methods used for classification of Population II stars in the Vilnius photometric system are described. An extensive set of standards with known astrophysical parameters compiled from the literature sources is given. These standard stars are classified in the Vilnius photometric system using the methods described. The accuracy of classification is evaluated by a comparison of the astrophysical parameters derived from the Vilnius photometric system with those estimated from spectroscopic studies as well as from photometric data in other systems. For dwarfs and subdwarfs, we find a satisfactory agreement between our reddenings and those estimated in the uvbyβ system. The standard deviation of [Fe/H] determined in the Vilnius system is about 0.2 dex. The absolute magnitude for dwarfs and subdwarfs is estimated with an accuracy of ≤0.5 mag.
