[AstroPy] Meteor Methods--Atmospheric Trajectories, PC Book on Astronmy

[Paul Barrett]

Wayne,

I am not familiar with the book, but your comment about astrometry
caught my eye.  We are currently implementing the plate reduction
methods as part of our work, actually on a much larger scale, of order
one million images.  These calculations should be easy to do in Python
for just a few images.  The important point is to properly set up the
arrays. You can then use the routines in scipy to do the least squares
adjustment.

I might be able to help if you can describe you problem in more detail.
