JetSeT is an open source C/Python framework to reproduce radiative and accelerative processes acting in relativistic jets,
allowing to fit the numerical models to observed data. The main features of this framework are:
-
handling observed data: re-binning, definition of data sets, bindings to astropy tables and quantities definition of complex numerical radiative scenarios: Synchrotron Self-Compton (SSC), external Compton (EC) and EC against the CMB
-
Constraining of the model in the pre-fitting stage, based on accurate and already published phenomenological trends. In particular, starting from phenomenological parameters, such as spectral indices, peak fluxes and frequencies, and spectral curvatures, that the code evaluates automatically, the pre-fitting algorithm is able to provide a good starting model,following the phenomenological trends that I have implemented. fitting of multiwavelength SEDs using
both frequentist approach (iminuit) and bayesian MCMC sampling (emcee) -
Self-consistent temporal evolution of the plasma under the effect of radiative, accelerative processes, and adiabatic expansion. Both first order and second order (stochastic acceleration) processes are implemented.

NOTE: Starting from version 1.1.0, python 2 is not supported anymore. Python >=3.8 is suggested, older python 3 versions (< 3.8) should work.
-
create a virtual environment (not necessary, but suggested):
conda create --name jetset python=3.9 ipython jupyter
conda activate jetset
-
install the code:
conda install -c andreatramacere jetset
if conda fails with dependencies you can try
conda install -c andreatramacere -c astropy -c conda-forge 'jetset>=1.2'
-
MacOS
- create a virtual environment (not necessary, but suggested):
pip install jetset
- create a virtual environment (not necessary, but suggested):
-
Linux
NOTE: currently, pip binaries for linux are not provided, so pip will build the binary on the fly. Hence:
-
install swig with of these methods and check that you have a C compiler (gcc)
-
pip install jetset
if fails, use one of the following methods
- Use anaconda
OR
- Install from source
OR
- Install the git release binaries from git releases
-
Install the git release binaries from git releases
pytest --disable-warnings --pyargs -vvv jetset.tests.test_users::TestUser
-
Get the source code from:
-
Uncompress the archive
jetset-stable.tar.gz
-
cd to the dir
cd jetset-stable
- Install requirements, run on the command line:
conda install --yes swig">=3.0.0"
conda install -c astropy -c conda-forge --file requirements.txt
if anaconda fails to install swig, you can try one of the following alternative methods
-
run on the command line:
python setup.py clean
python setup.py install
-
run the test (optional, run all the examples outside the installation dir)
cd ~/
mkdir test_jetset
cd test_jetset
pytest --pyargs -vvv jetset.tests.test_users::TestUser
-
Install requirements, run on the command line:
pip install swig>=3.0.0
pip install -r requirements.txt
if pip fails to install swig, you can try one of the following alternative methods
-
run on the command line:
python setup.py clean
python setup.py install
-
run the test (optional, run all the examples outside the installation dir)
cd ~/
mkdir test_jetset
cd test_jetset
pytest --pyargs -vvv jetset.tests.test_users::TestUser
The following python packages are required:
python =3.9 (python 3.9 is suggested, older python 3 versions should work, python 2 is not supported any more from version>=1.1.0)
setuptools
scipy
numpy
astropy
matplotlib
swig
future
iminuit
corner
six
emcee
pyyaml
numba
sherpa
A C compiler is also necessary, plus the SWIG wrapper generator.
All the dependencies are installed following the Anaconda method OR the pip method, as described above.
