I asked when it was known that the Sun moved with respect to
other stars on sci.astro ("When did we establish..."). I
received this response from Mike Dworetsky:
<QUOTE>
The Sun's motion of c. 20 km/s with respect to the local stars
had been
known for a long time by then (since William Herschel, around
1790-1800),
but is a constant velocity.
<END QUOTE>

And Peter Webb pointed out that this effect should have been
vectorially additive to the Earth's motion around the Sun. The
fact that it wasn't included is beyond me.
