Re: dB timings - RE: A Data Reduction Proposal

[<aah@nofs.navy.mil>]

Rob,
  For your timings, and I apologize ahead of time for
not following the entire discussion, was the import and merging
of 200K "stars" basically a single-filter detection of 200K
separate stars that you then add to the database?  The
reason I ask is that the baseline that was discussed many
moons ago for a single night was the following:
     [200 2kx2k images (100 each V and I), each with 5K stars]
that is 1M entries per night to add to the database if I've done my
math right.  If your estimate of 7hrs for 200K stars is
right, then 35 hours would be required to import/merge one night
of data from one site with your computer.  This doesn't depend on the size
of the database?  My estimate is about 60M real stars will be present
in the Mark IV database, along with an approximately equal number of
nonreal objects.
