Redukuoto savojo judėjimo diagramų analizė / Analysis of reduced proper motion diagrams

The purpose of this paper is to compose reduced proper motion diagram (RPMD) and to perform its analysis. The stars that has MKK system or those belonging to the group of subdwarf, white dwarf and metal-deficient. From possessed data catalog known binary stars were excluded. Color excess EB-V in this paper was calculated in the following two ways: •Using MKK system; •Using Shlegel method (including distance to the star). Color excess average that was calculated from EB-V results found using two above presented ways was used for 1-5 luminosity classes. calculated according to Shlegel method was used for subdwarf and metal-deficient stars. Taking into account that white dwarfs are near stars, EB-V was equated to 0. Following parameters were calculated in this paper: interstellar extinction AV, reduced proper motion HV, and absolute magnitude MV. Accuracy of used parameters was analysed. Having composed RPMD separately for each luminosity class, distribution areas of the stars were localysed by two intersecting lines. Obtained RPMD was compared to the Jones reduced proper motion diagram. Identified relation between MV and HV was approximated with line.
