simtools

LICENSE release DOI pypyi

simtools is a modular toolkit for managing simulation model parameters, configuring, running, and validating simulation productions for arrays of imaging atmospheric Cherenkov telescopes.

Documentation: simtools documentation

simtools is part of the SimPipe pipeline of the Cherenkov Telescope Array Observatory (CTAO).

Authors: see the CITATION.cff file. Contributors: see the Contributors page.

Note simtools is under active development. Contact the developers before using it: simtools-developer@desy.de

Features

  • Simulation model libraries and management
  • Interfaces for reading simulation model parameters from the CTAO Simulation Models repository
  • Tools for preparing, configuring, running, and validating simulation productions
  • Applications for deriving and validating model parameters (see CTAO Model setting and validation workflows)
  • Standardized interfaces and outputs independent of the simulation software (e.g., CORSIKA air shower simulations and sim_telarray telescope simulations)
  • I/O and reporting tools for simulation models and production data

Quick Start

For users:

pip install gammasimtools

Copy .env_template to .env and update the file to set up your environment.

For developers:

git clone https://github.com/gammasim/simtools.git
cd simtools
python -m venv .venv
source .venv/bin/activate
# rehash (to avoid shell mixup in certain envs)
pip install -e '.[tests,dev,doc]'
