A repo for tools related to gammapy background generation. This is the public version of gammapy-background-analysis.
This package requires V2DL3 and Gammapy to be installed.
Gammapy (v1.1) can be installed via:
pip install gammapy==1.1
Also install gammapy-data using
gammapy download datasets
And set the environmental variable GAMMAPY_DATA, to that download location (for example):
export GAMMAPY_DATA=/path/to/gammapy/data
A modified version of Hipparcos_MAG8_1997.dat is used for finding stars. Copy this into the $GAMMAPY_DATA/catalogs/ directory:
cp gammapy_tools/Hipparcos_MAG8_1997.dat $GAMMAPY_DATA/catalogs/
As there maybe issues installing root-numpy, V2DL3 can be installed in one's environment as follows (replace mamba with conda for a conda install):
git clone https://github.com/VERITAS-Observatory/V2DL3.git
cd V2DL3
# Because its an env install of requirements
# Note the python version in the latest test throws issues with pytest
grep -A 100 "dependencies:" environment-eventdisplay.yml | grep "-" | grep -v "python" | awk '{print $2}' | xargs mamba install --yes
# root_numpy throws issues too. Only VEGAS uses it
mv setup.py _setup.py && grep -v "root_numpy" _setup.py > setup.py && pip install .
# clean up
cd ../ ; rm -r V2DL3
gammapy_tools can then be installed via:
pip install .
For details on working with containers see containers.md
A number of worked examples can be found in examples.
To simplify analysis, a "driver" config file is used. An example of such a config file is shown in gammapy_tools/templates/config.py, which contains 4 crab runs. A config can be generated using:
from gammapy_tools.templates import get_config
config = get_config()
- See config.md for details on config files.
- See mimicing_data.md for details on mimicing and scrambling data.
