This repository contains the code to analyze data from the ARCONS array.

Environment variables that need to be set:

MKID_RAW_PATH - path to the root of the raw data directory structure MKID_PROC_PATH - path to the root of the processed data directory structure MKID_BEAMMAP_PATH - path to the default beammap file to be used by h5quicklook.py (only used for quicklook)

gittle -- represents the state of the git repository in python (easy_install gittle)

ds9 -- need to download pyds9 and install. Download the package from the download/pyds9 section of the ds9 web page: http://ds9.si.edu See instructions at: http://hea-www.harvard.edu/RD/pyds9/

If you are having troubles with PyTables (which you shouldn't since it is built into EPD), see http://www.tumblr.com/tagged/pytables and instructions therein for Mac.

We also use astropy. The version on Turk is 0.3.1 Anaconda installs a newer version which is pretty much the same, but in some code this import needs to work:

from astropy.stats.funcs import sigma_clip

Newer versions of astropy have something called astropy.stats.sigma_clipping which may or not may not be the same algorithm.

To make nicer looking plots, you need the packages configobj and mpltools

$ easy_install configobj $ git clone git@github.com:tonysyu/mpltools.git $ cd mpltools $ python setup.py install

Another package you will need is pyinterval. It depends on crlibm

NOTE: the python package interval is not the same thing. If this got installed by mistake, things might not work so well. A tell-tale sign that you have the correct thing installed is that this line works in ipython:

from interval import interval, inf, imath

On Turk, these packages installed in the usual way without fuss.

On bender, there was a problem with the how libcrlibm.a was build: relocation R_X86_64_32S against `.rodata' can not be used when making a shared object; recompile with -fPIC

To fix this, in the crlibm source tree,in scs_lib/Makefile add the -fPIC option in this line: CPPFLAGS = -fPIC

On a Mac, you need to do this:

I downloaded crlibm-1.0beta4.tar.gz from http://lipforge.ens-lyon.fr/www/crlibm/

$ untar $ configure $ make $ sudo make install.

Then I downloaded pyinterval-1.0b21.tar.gz from http://pypi.python.org/pypi/pyinterval and untarred it.

Here is the tricky part.

in setup.py pyinterval, change the lines near the end from this

         include_dirs = ['/opt/crlibm/include'],
         library_dirs = ['/opt/crlibm/lib'],

to this

        include_dirs = ['/usr/local/include'],
        library_dirs = ['/usr/local/lib'],

and then

python setup.py build sudo python setup.py install

The tests in cosmic/TestTimeMask.py uses the class Cosmic which uses this, and it will also be used to locate times to mask hot pixels.

• NOTE - Had to reinstall this recently, and had little trouble - think I just did 'pip install pyinterval', or 'easy_install pyinterval', and it went just fine (on MacOS Mavericks). JvE, 11/5/2014.

Note that in the photonlist package/directory you will need to compile the fortran routine 'boxer.f'. This should do the trick:

f2py -c -m boxer boxer.f

... After running that, you can check it works in python by trying to import with 'import boxer' at the python command line. See the readme.txt file in photonlist/ for (possibly) more info.

Getting it working on bender during the Palomar 2013 run.

Bender has the canopy version of python installed. To get pyqt working:

yum install qt4

I then tried yum install PyQt4 but the canopy version of python did not pick it up.

sudo scp -r stoughto@turk.physics.ucsb.edu:/usr/local/epd/lib/python2.7/site-packages/PyQt4 . This needs the same version of sip. On turk, sip -V says it is version 4.13.2 so I downloaded sip-4.13.3.zip, unzip, python configure.py; make; sudo make install.
