Tools to perform the periodicity analysis of gamma-ray emission from pulsars. It focuses on the data from the LST-1 telescope of the future CTAO gamma-ray observatory. It is built on top of Gammapy and PINT libraries.
- Modelling and calculation of phases with LST-1 and Fermi-LAT data
- Statistics, building phaseograms and search for pulsations with LST-1 and Fermi-LAT data
The easiest way to install the package is by cloning the repository and creating a new environment using environment.yml
git clone https://github.com/cta-observatory/PulsarTimingAnalysis.git
cd PulsarTimingAnalysis
mamba env create -n pulsar-lst1 -f environment.yml
conda activate pulsar-lst1
pip install .
Note: For macOS users with M chips, you may need to install the package c-blosc2 first (since lstchain requires python-blosc2, which is not available for M chips architectures):
mamba create -c conda-forge -n pulsar-lst1 python=3.11 c-blosc2 protozfits=2 protobuf=3.20
Then install PulsarTimingAnalysis with the rest of the dependencies with pip install . after activating the environment.
