Gentlepeople:
I'm going to implement some astronomical image processing stuff
using the Matrix extensions. I think it's a perfect application for
Python- I need to perform arithmatic on 2MB numerical arrays quickly and
efficiently, while dealing with some simple variables associated with
each array. I could post more details if there is interest-
Anyway, the question is how to most efficiently read in data already
written to disk in a standard format (FITS). I know how to parse
the headers, its the 2 MB data arrays I'm worried about. I'm thinking about
reading the data using the array module, and feeding the result of that to the
Numerical module. Is that reasonably efficient? It seems like I'll have 2
copies floating around for a moment. Is there another mechanism
in the Numerical module that I'm missing?
Thanks for any help- this stuff looks great, and answers needs I've had
for some time!
