Re: Tycho-2 catalogue



Brian,

Thank you for your comments.  I stand ready to do the work once a few like 
you give me the guidance as to what to do.  Yes, I am asking for a little 
work from you now.  Possibly some of you can get together and share the 
generation of a reference catalog.  You will be rewarded by many times the 
effort in the generation of the Mark IV catalog.

I don't have the knowledge or experience to do things right from the 
start.  So I have to depend on the experts who watch this list.  As Arne 
points out, I don't always listen the first time.  This is because I don't 
always know enough to listen or how to sort out the good advice from the 
bad.  Sorry, I don't just accept expert advice, I have to understand it.  I 
have been burned too many times by experts in High Energy Physics.

A little work from the experts now will get a good catalog.  I have the 
instruments built to cover the northern sky with many observations per 
year.  I already have several times the tenxcat and more is being collected 
every clear night.  I don't want to make more than two more passes through 
the data as it is getting to be a big job to process all that I have.
