I've created the following table of Known Extra-Solar Planet RA/DEC's
to help me to cross-compare their positions to the SETI@home Stellar
Countdown WU RA/DEC's (very kindly sent to me.)

Why?  The detectability of extra-solar planets is normally considered
a contra-indication of intelligent life because the habitable zone is
compromised.  Also, detectable ones tend to have already been subjected
to targetted SETI and tend to be relatively close (S@H is really best
for targets that are too far to be considered for a targetted search).

The main value of extra-solar planets is that their detection increases
the estimated likelihood of planets in general, not in providing specific 
candidates.

(My impression is that one of the reasons for not publishing detailed
coordinates is to discourage this sort of speculation.)
