The analysis of X-ray spectra often depends on the correct usage of instrument response files. However, these calculations are exclusively implemented in one of the three X-ray packages, all of which come with a lot of overhead.
Here, we attempt to separate out and simplify the response calculation in sherpa for ease of use with any other (user-written) code.
Clàrsach currently lives exclusively on GitHub (we might upload it to pip once it's a little better developed).
Please note: Clàrsach comes with a suite of tests and test data sets that checks whether the code words for a range of different X-ray telescopes. We strongly urge you to download the test data and run those tests! We provide instructions for both with and without the test data.
Because the test data files are large, we do not keep them in the repository, but
in a system called the Git Large File System (git lfs).
This is an extension for git maintained by GitHub, and can be downloaded on the
git lfs website or your favourite package manager.
In order to download the repository with the test data, you then move to the directory where you wish the code to live and type::
git lfs clone git@github.com:dhuppenkothen/clarsach.git git lfs pull origin master
Then move into the clarsach directory. You can install the package by running:
python setup.py install
Depending on your python installation and set up, this may require administrator privileges.
Finally, run the tests using py.test (you may need to install that, too)::
py.test
Hopefully, this should run without throwing errors. If it does, please contact us through the issues.
You can use standard git for cloning the repository, but be aware that the test data will not be downloaded.
In order to download the repository, do the following::
git clone git@github.com:dhuppenkothen/clarsach.git
In order to install it, you move into the clarsach directory this will
create and do the following::
python setup.py install
This should install Clàrsach on your system. Please note that your permissions
might require you to use sudo in order to install the package.
