+
+  Velocity component in a given direction due to the rotation
+  of the Galaxy (single precision)
+
+  Given:
+     R2000,D2000   real    J2000.0 mean RA,Dec (radians)
+
+  Result:
+     Component of dynamical LSR motion in direction R2000,D2000 (km/s)
+
+  Sign convention:
+     The result is +ve when the dynamical LSR is receding from the
+     given point on the sky.
+
+  Note:  The Local Standard of Rest used here is a point in the
+         vicinity of the Sun which is in a circular orbit around
+         the Galactic centre.  Sometimes called the "dynamical" LSR,
+         it is not to be confused with a "kinematical" LSR, which
+         is the mean standard of rest of star catalogues or stellar
+         populations.
+
+  Reference:  The orbital speed of 220 km/s used here comes from
+              Kerr & Lynden-Bell (1986), MNRAS, 221, p1023.
+
+  Called:
+     slCS2C, slVDV
