Starfish is a set of tools used for spectroscopic inference. We designed the package to robustly determine stellar parameters using high resolution spectral models, however there are many potential applications to other types of spectra, such as unresolved stellar clusters or supernovae spectra.
Beta version 0.2
Please note that this software package is still under development as more features are being added.

Starfish has several dependencies, however most of them should be satisfied by an up-to-date scientific python installation. We highly recommend using the Anaconda Scientific Python Distribution and updating to python 3.3 or greater. This code makes no attempt to work on the python 2.x series, and I doubt it will if you try. This package has been tested on Linux and Mac OSX 10.10.
Starfish requires the following Python packages:
Unless you actively maintain your own scientific python distribution, I recommend installing the Anaconda distribution with python 3.3 or greater , obtainable here. All of these required packages can be installed via Anaconda by doing
conda install pkg where
pkg is the name of the package you want to install.
To make sure you are running the correct version of python, start a python interpreter via the system shell and you should see something similar
$ python Python 3.4.1 (default, May 19 2014, 17:23:49) [GCC 4.9.0 20140507 (prerelease)] on linux Type "help", "copyright", "credits" or "license" for more information.
If your shell says Python 2.x, try using the
python3 command instead of
For now, we recommended building Starfish from source on your machine. Once the features stabilize, there will be an option to install via
In order to download a local copy of this repository,
cd to the location where you want it to live and then do
git clone firstname.lastname@example.org:iancze/Starfish.git cd Starfish
To build the cython extensions
$ python setup.py build_ext --inplace
Since you may want to edit files during active development, it is best to install in
$ sudo python setup.py develop
You should now be done. Once the package has stabilized, the
develop command may change to
$ sudo python setup.py install
To test that you've properly installed Starfish, try doing the following inside of a Python interpreter session
>>> import Starfish
If you see a blank line, then the package successfully installed. If you see any errors, then something went wrong--please file an issue.
Now that you've successfully installed the code, please see the documentation on how to begin using Starfish to solve your spectroscopic inference problem, or head to the cookbook for a taste of a typical workflow.
