The heliocentric radial peak velocity for K i and Na i are shown in a sky coordinate (right ascension and declination) plot. The radial velocity of the gas (in the diffuse ISM) in Upp Sco is highest in the upper-left corner, the material is approaching with velocities up to 15 km s^-1 (along the line-of-sight). The gas in the lower-right corner has the lowest velocity (with respect to the Sun). (See on-line electronic version for colour figure.)
