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.

BGPS data paper published
Metalinking! The BGPS paper finally made it onto astro-ph today. It will be published in ApJS before the year's end.
Links to all of the published BGPS papers at the Bolocam Data Team website
And just because I want more linking, here they all are again:

Neat new things....
1. sptool is a quick way to compare standards to stellar spectra. Nice, I'd been looking for a tool like that.
2. GNU screen captions are useful especially when working in a screen-within-a-screen environment (who does that, really?)
3. finally got SPLAT to work... turns out I just hadn't reduced my damned data
4. kill -STOP and kill -CONT are really useful ways to pause programs that are sucking up resources if you want to resume them later. Haven't tried this on "real" code yet.

Filled step plots in matplotlib
It's not possible to do a simple filled step plot in matplotlib using default
commands. Workaround:
commands. Workaround:
def steppify(arr,isX=False,interval=0):
"""
Converts an array to double-length for step plotting
"""
if isX and interval==0:
interval = abs(arr[1]-arr[0]) / 2.0
newarr = array(zip(arr-interval,arr+interval)).ravel()
return newarr
plot(xx,yy,linestyle='steps-mid',color='b',linewidth=1.5)
fill_between(steppify(xx[x1:x2],isX=True),

Histogram in Google Spreadsheet
It's not easy to make a histogram in google spreadsheets without replicating data. The "countif" function would be great, except it only allows very simple criteria. However, there's a workaround:
=count(Filter('Grades'!V2:V30,'Grades'!V2:V30>0.9))
=count(Filter('Grades'!V2:V30,'Grades'!V2:V30<0.9,'Grades'!V2:V30>0.8))
The Filter() function returns an array, which can be operated on like any other set of cells.
It's still not easy to make a nice-looking histogram, but the output of this process is at least usable.
=count(Filter('Grades'!V2:V30,'Grades'!V2:V30>0.9))
=count(Filter('Grades'!V2:V30,'Grades'!V2:V30<0.9,'Grades'!V2:V30>0.8))

Ghostscript error?
I've been receiving the following error when attempting to compile (ps2pdf) my w5 outflows paper:
I get the same error with Ghostscript 8.64, but on my laptop, using the fink version, it works. Similarly, there are errors with the postscript, so I'm led to believe it's an error in latex:
No idea what the cause is but it's time to start documenting steps and looking for a workaround. Compiling on the lappy isn't a good option.

EVLA information
It has been really hard to find EVLA information like beam size, largest angular scale, sensitivity, etc. on the VLA pages because all of the google searches point to old VLA information. The most useful and recent EVLA information on beam size and largest angular scale is here

RATRAN on Mac OS X
Mac OS X doesn't like the defaults built in to RATRAN. It died unhappily with errors like:
and
In order to get it to run, I had to do the following:
ld_classic: can't locate file for: -lcrt0.o
and
ld: warning: in /usr/local/lib//libcfitsio.a, file is not of required architecture
In order to get it to run, I had to do the following:
- Install CFITSIO with
CFLAGS="-arch x86_64 -arch i386 -g -O2"
to /usr/local/lib
- Edit the sky/Makefile OPT variable (line 23) to read:
OPT = -I. -O2 -fno-automatic -arch x86_64

IRAF append/prepend/replace
IRAF has special syntax to append/replace, so you can do something like:

imarith *.fits - dark.fits ds_//*.fits
...though I can't remember right now how to do replacement etc.

command line & escape key
Problem: in both the bash command line and ipython, if I hit escape twice, I can never again do history-search-backwards (i.e. when you type part of a command and type "up" and reverse-search through your command history). Any idea how to fix this?

Rebuilding python from scratch again
I got scipy working a week or two ago, but doing so killed matplotib's tkagg. So, I switched to the MacOSX backend, which worked ok until I realized that the interactive (connect) features of macosx failed miserably. This led me to try to get matplotlib working.... which broke with those awful "symbol not found" errors in ft2font.so and _path.so, which I've determined all have to do with linking to the wrong library files.
The most worrisome part of this process was discovering that a full Time Machine recovery of /usr and /Library/Frameworks and /Library/Python did *not* restore python - it stayed dead with IDENTICAL errors. So there are probably additional layers of hidden links.
The process below is based on hyperjeff's blog post but differs substantially based on Sam Skillman's recommendations and the very big issue I ran into that my /usr/local files appeared to be corrupted. After this install, my path no longer includes /usr/local/bin and /sw has been moved to /_sw... hopefully one of these days I'll be ballsy enough to delete it.

DS9 gaussian fitting
One thing DS9 desperately needs is an interactive gaussian fitter. I have NOT implemented one yet, but it is high on my to do list. Has anyone else (googlers?) tried or succeeded in implementing such a thing? Ideally, something with NO dependencies: if I write one, it will require python, numpy, and probably pyds9 - ick. Straight-up TCL would be very much preferable.
Another attempt to get 64 bit python on Snow Leopard
Sam Skillman posted his attempt to get 64 bit python on snow leopard. It worked, but you need to install python with --enable-framework and NOT --prefix and NOT --enable-universalSDK. It is 64-bit only, not universal: universal causes trouble.

After yesterday's disastrous attempt to install various python packages, I started from scratch. First, I got rid of all of my python frameworks (backed up but removed from the path). Then, I compiled python 2.7 from scratch:
I got some help from http://blog.mahmoudimus.com/2009/12/python-2-6-4-and-twisted-9-on-os-x-10-6-snow-leopard/
I'm not concerned about these - I don't use any of them and I assume I need to install some other packages to get them to work.
During make test, I had two failures that resulted in "python crash" pop-up boxes:
Then, I got some malloc errors:

To find the necessary bits, look in setup.py in detect_modules() for the module's name.

Installing Snow Leopard
I'm going to attempt to install snow leopard today. This post will serve as a record of the difficulties I run into.
Things to install (and ensure they are 64-bit):
Things that have happened:
Things to install (and ensure they are 64-bit):
- ipython
- numpy
- scipy
- matplotlib
- stsci-python
- starlink
- gfortran
- latex
- idl (check)
Things that have happened:
- Had to restart again (twice) to install additional updates
- My bash command line looked funny - something about bash changed, but I don't know what. The fix was easy: commented out some code from http://pseudogreen.org/blog/set_tab_names_in_leopard_terminal.html that I had been using to set the tab title
- My locate db broke. Needed repair:
sudo /usr/libexec/locate.updatedb
- numpy svn failed to build:
python setup.py build

RuntimeError: Broken toolchain: cannot link a simple C program
SOLUTION: Use the Mac OS X 10.6 python (/usr/bin/python). I will do this until I run into another problem. Numpy build successfully - Build/install matplotlib - failed! Completely!
- Acquired gcc/gfortran from hpc
- Followed instructions from hyperjeff on fortran install...
- Get rid of numpy 1.2.1:
mv /System/Library/Frameworks/Python.framework/Versions/2.6/Extras/lib/python/numpy /System/Library/Frameworks/Python.framework/Versions/2.6/Extras/lib/python/.not_numpy.bak
- Try to install scipy. Fail on missing umfpack, follow hyperjeff's instructions (but make sure to edit the site.cfg in scipy, not just the one in numpy)
Had to add the following code:
sudo cp AMD/Lib/libamd.a /System/Library/Frameworks/Python.framework/Versions/2.6/lib
sudo cp UMFPACK/Lib/libumfpack.a /System/Library/Frameworks/Python.framework/Versions/2.6/lib
sudo cp AMD/Include/amd.h /System/Library/Frameworks/Python.framework/Versions/2.6/include
sudo cp UFconfig/UFconfig.h /System/Library/Frameworks/Python.framework/Versions/2.6/include
sudo cp UMFPACK/Include/*.h /System/Library/Frameworks/Python.framework/Versions/2.6/include - Installed fftw from fftw.org with simple ./configure, make, sudo make install - no compiler opts as they killed the install
- Get SoundSource from rogueamoeba
- Updated istatmenus

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

Logarithmic Colormap / Other Colormap in Matplotlib
This is kind of a pain to find out:
It also works for contours, and can be particularly useful if you only want to display contours at a few levels, but you want the colormap to start at a different point. e.g.:
will start at light blue instead of dark blue in the default colormap
from matplotlib.colors import LogNorm
im = imshow(.... cmap=... , norm=LogNorm(vmin=clevs[0], vmax=clevs[-1]))
It also works for contours, and can be particularly useful if you only want to display contours at a few levels, but you want the colormap to start at a different point. e.g.:
contour(xx,levels=[2,3,4,5,6,7,8,9,10],norm=matplotlib.colors.Normalize(vmin=0,vmax=10))
will start at light blue instead of dark blue in the default colormap

my month of travel
I figure most people spending a month away from home would bring more than a small duffel full of clothes. I was quite satisfied with what I had. The things I missed (as a reminder for next time):
My desktop, eta
My music collection
Powerbars
...nothin else, really
