Radial velocity (cz) with respect to the CMB: v3k
It is calculated from the heliocentric velocity v
using the total solar motion of 370.06 km/sec towards the direction defined by
Galactic coordinates (263.914°, +48.2646°) (Planck 2015 results):
vlg = v + 370.06 ( sin(-6.894522°)sin(de2000) + cos(-6.894522°)cos(de2000)cos(167.889229°-al2000) )
