I realize this topic is a bit old, but I couldn't help but add
something I forgot to mention earlier...
I mean, once the computations are moved elsewhere numpy is basically a
convenient way to address memory.
That is how I mostly use NumPy, though. Computations I often do in
Fortran 95 or C.

Here is what I know about the chararray usage at STScI since first
looking into it this morning.
It is used in PyFITS and within the COS instrument calibration code.
I have not heard back from the other projects yet given most of our
developers are away at this time.

Are you sure that those are exactly the commands that you executed?

nope.

cheers,
I agree with David's comments. In that theme I have removed
scipy.stsci from scipy. Users get it directly from us at STScI via
STSCI_PYTHON. It doesn't have any documentation in the doc system.
It isn't by default in the scipy namespace. And as a recent bug
report indicates they can't

Hi Chris Stefan,
I will be around for most of the weekend (as I believe will Perry).
I'm not sure I'll be able to contribute a lot to coding, but if
there's any stuff you want to co-ordinate between STScI and Stefan's
scikit, let me know if I can help. That's probably about the most
useful thing
