Re: Tycho-2 catalog

[Tom Droege <tdroege2@earthlink.net>]

Yea!  Thank you Arne.  Who knows, you have offered lots of good advice that 
I did not know how to take.  One sometimes has to suffer before good advice 
can be accepted.  ;^)

The astometry works very well now, thanks to Michael's last 
change.  Hopefully I can figure out how to use a better catalog just for 
the photometry.
