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 git@github.com: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:
python example/tractor-sdss-synth.py
Prereqs:
- scipy (> 0.7; 0.9 works)
- numpy (>= 1.4)
- astrometry.net (often svn trunk is required)
Other packages used in various places include:
Horribly incomplete, but online at http://thetractor.org/doc
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!
