simtools

Simulation tools and applications for the Cherenkov Telescope Array (CTAO).

simtools provides:

• libraries for simulation model definition and management
• model database interfaces
• tools for the preparation and configuration of simulation productions
• applications for simulation model parameter derivation and validation
• standardized interfaces and data products independent of the underlying simulation software (e.g., CORSIKA, sim_telarray)
• I/O and reporting tools for the MC simulation model parameter and production database

simtools is one part of the CTAO Simulation Pipeline, which consist of the following components:

• CORSIKA air shower simulation code and the sim_telarray telescope simulation code
• simulation model parameter
• databases, especially the model parameter database

:::{note} simtools is currently under heavy development with continuous changes and additions planned. Please contact the developers before using it: simtools-developer@desy.de. :::
