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
- Simulation model libraries and management
- Database interfaces for simulation model parameters (see CTAO Simulation models)
- 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 the simulation model and production database
