solar motion in direction R2000,D2000 (km/s). The Local Standard of Rest used here is one of several "
kinematical"
LSRs in common use. A
kinematical LSR is the mean standard of rest of specified star catalogues or stellar populations.
The Sun’
s motion with respect to a kinematical LSR is known as the "
standard"
solar
motion.
There is another sort of LSR, the "
dynamical"
LSR, which is a point in the vicinity of the Sun
which is in a circular orbit around the Galactic centre. The Sun’
s motion with respect
to the dynamical LSR is called the "
peculiar"
solar motion. To obtain a radial velocity
correction with respect to the dynamical LSR use the routine palRvlsrd.
