Repositories for observers

I should have posted these a while ago....
casaradio is a subversion repository for folks at The Center for Astrophysics and Space Astronomy at CU Boulder to post radio astronomy related codes. So far, emphasizes single dish (GBT, Arecibo), but will include EVLA, CARMA, and ALMA eventually.
aposoftware is a similar page, but is a mercurial repository and is meant to include instrument-specific software for the Apache Point Observatory 3.5m telescope. Right now includes a TUI script or two and the TSPEC and DIS IRAF-twodspec pipelines.

I'd be remiss to leave out the BGPS pipeline even though it's mentioned on the previous post.

Also, agpy is my personal code repository.

PSDs, cross-correlation...

scipy is capable of doing fft-base cross-correlation, convolution, etc., but it requires the stsci package, which is not generally easy to install. For that matter, scipy can be a pain some of the time. So agpy now includes a 2D cross-correlation code and a power spectrum / power spectral density code. These are pure-numpy codes that should be easy to use without any other bothersome dependencies.

EDIT: I have them check for scipy (which can cause crashes if you have a bad scipy install, e.g. 32 bit executables on a 64 bit system) because scipy uses FFTW and numpy appears not to. Also, this code & related stuff has been discussed on astrobetyter
