  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.
