Query: Measuring the absolute total intrinsic redshifts (surface gravity plus
  the convective blueshift) of the main sequence stars and red giants using
  GAIA data   We analyze the GAIA release II data to demonstrate how one can measure the
absolute total intrinsic redshifts of the main sequence stars and red giants.
We remove the relative velocity components of the stars' motion with respect to
the sun by doing the analysis in the local standard of rest (LSR) frame defined
by the average stars' motion. We provide results for four different types of
stars. F, G and K types of stars have about the same value of intrinsic
redshift, which is however much smaller than the expected gravitational
redshift. This indicates that the GAIA's data include convective blueshift
effect of a several hundreds m/s magnitude. The red giants' intrinsic redshifts
are negative, which implies that their convective blueshift is stronger than
the gravitational redshift. This is expected since red giants are far less
compact than other types.
