UmbralRaptor: what is aberration and light deflection in this context
<egg|zzz|egg>
also what is space motion
<UmbralRaptor>
space motion is the full 3D motion of the stars themselves. While they use α', δ', and radial velocity, it's sometimes listed as u, v, and w

abberation is an apparent change in stellar positions from changes in earth's velocity (that is, 30 km/s one way to 30 km/s the other over 6 months). IIRC, it's large compared with parallax, but affects all stars in a distinct pattern.

bofh: swiss news: the cows are too large
<BPlayer>
"[...] said group spokesman Hans Rüssli." God, such a name can really only be found in Switzerland.

Anyway, /me is off

See you guys!
