Re: [TASS] Mari IV Data Processing Progress Report

Glenn,

That is just great!  Hmmmm!  I figure about 5000 frames a year from my
location.  This is 20,000 minutes of processing or 300 hours.  Not so bad.
That then gives 100 million star measurements, or 50 million pairs.

I do not fear.  Intel will have the processor ready that we need by the
time we need it.  Or IBM or ...  Copper will save the day.

Did you try to pair match?  How many pairs out of the 18k V and 21k I stars?
