Galactic model parameters for field giants separated from field dwarfs by their 2MASS and V apparent magnitudes

Abstract

We present a procedure which separates field dwarfs and field giants by their 2MASS and V apparent magnitudes. The procedure is based on the spectroscopically selected standards, hence it is confident. We applied this procedure to stars in two fields, SA 54 and SA 82, and we estimated a full set of Galactic model parameters for giants including their total local space density. Our results are in agreement with the ones appeared recently in the literature.
