To check out and build the code in a tractor directory:
wget -O - https://raw.github.com/dstndstn/tractor/master/checkout.sh | bash cd tractor
Or if you prefer:
# # Grab and install the Astrometry.net code (http://astrometry.net/downloads) # and then... # git clone firstname.lastname@example.org:dstndstn/tractor.git cd tractor make
It is possible to run directly out of the checked-out tractor directory. But if you want to install it:
make python setup.py install # --prefix=/some/place or maybe --home=/your/place
There is a test script that renders SDSS images:
- scipy (> 0.7; 0.9 works)
- numpy (>= 1.4)
- astrometry.net (often svn trunk is required)

We are trying to move from a "Research code that only we use" phase to "Research code that other people can use". We are happy to hear your feedback; please feel free to file Issues. And naturally we will be pleased to see pull requests!
