%T simtools - Simulation tools and applications for the Cherenkov Telescope Array (CTAO)
%M PUBDB-2025-04860
%D 2025
%X This release of simtools, the simulation toolkit for the CTA Observatory, includes the following main changes: Bugfixes Bugfix in validation of generated sim_telarray configuration: missing assert on the outcome of the tests (tests always passed, even with differences). (#1856) Fixed array trigger file generation to properly combine non-hardstereo telescopes. Previously, each telescope type generated separate trigger lines, preventing software stereo triggers between different telescope types (e.g., SST+MST). Now hardstereo lines remain separate while non-hardstereo telescopes are combined into a single line, enabling cross-telescope-type triggering. (#1863) New Features Add new simulation model parameter transit_time_random. (#1808) Implement version check for model parameters for any software type. (#1842) Add possibility to define new base models taking into account the correct history of models for simtools-maintain-simulation-model-add-production. (#1844) Add possibility to change model parameters from command line using the -overwrite_model_parameters command line parameter. (#1850) Maintenance Change source of simulation model database in CI to 'main' branch of simulation model repository. Tests against the latest release versions for simtools release candidates (1.2.3-rc). Allow to configure simulation model repository branches for manually triggered workflows. (#1846) Review and update all XPASS unit tests. (#1855) Simulation model Change default simulation models database version to 0.11.0. (#1852)
