This release of simtools, the simulation toolkit for the CTA Observatory, includes the following main changes:

API Changes

  • Rename general.ensure_iterable to general.ensure_list to clarify function intent (API change). (#2191)

Bugfixes

  • Fixed bug in ground-to-shower coordinate transformation of passing angles in degrees where radians are expected. Fixed coordinate system orientation for transformation. (#2194)
  • Add 'moon' NSB level to legacy simtel writer. Fix TypeError when writing HDF5 tables with object-dtype string columns (e.g. file_name in FILE_INFO). (#2210)
  • Fix model parameter validation for dimensionless floats. (#2222)
  • Fix bug in overwrite-model parameter mechanism for configuration_sim_telarray parameters: parameters were set for all telescopes, rather than only for the specified ones. (#2228)
  • Fix instrument field in model parameter schema and restrict it to allowed names defined in common_definitions.schema.yml. (#2232)

New Features

  • Add functionality for generating job configurations for a parameter grid to simulate_prod_htcondor_generator. (#2174)
  • Add Apptainer generation step to simtools-prod container production step. (#2175)
  • Add functionality to production_derive_corsika_limits and plot_simulated_event_distributions to read in several event data files using glob patterns. (#2176)
  • Add feature to allow for user-defined cosmic-ray spectra on the trigger rate application. (#2177)
  • Add an event-level production comparison application with multi-production trigger-distribution plots. (#2181)
  • Add the possibility to run the derivation of CORSIKA limits in parallel - e.g. for several zenith angles. (#2182)
  • Improve derivation of CORSIKA limits and allow to define a loss fraction per energy bin ('differential loss'). (#2185)
  • Major improvements to simulation production configuration preparation with clear separation introduced between observation grid generation and backend submission code.
    Allow NSHOW to follow a pre-defined power law for simulation production grid definition. (#2190)
  • Add application to plot CORSIKA limits. Rearrange limits plotting for production_merge_corsika_limits.py. (#2196)
  • Add schema for CORSIKA limits tables. (#2203)
  • Add zenith-angle scaling mode for showers_per_run in production grid generation (#2207)
  • Add a file collection step to simtools-run-application. (#2215)
  • Allow integration tests to be run from any directory, not only the simtools base directory. (#2216)
  • Add glob-pattern collection, multi-output-path support, and zenith/azimuth/NSB-encoded plot filenames to simtools-production-derive-corsika-limits. (#2219)
  • Add illuminator_telescope_visibility model parameter schema (#2220)
  • Allow a single telescope name (e.g., MSTN-05) as array_layout_name, automatically creating a single-telescope layout without requiring a database entry. (#2221)
  • Add illuminator-telescope visibility model parameter and parallel multi-pair simulation support. A new illuminator_telescope_visibility schema defines which telescopes each illuminator can reach. The simulate_illuminator application gains --simulate_all and --max_workers options to run all valid pairs in parallel via the new MultiIlluminatorSimulator class. (#2224)

Maintenance

  • Move code from application scripts into modules to improve unit test coverage and maintainability. (#2162)
  • Improve event data list reading performance. (#2180)
  • Add unit-test skill to support Copilot. (#2187)
  • Add CI tests to ensure that every simtools Python module has a corresponding unit test module. (#2193)
  • Minor fixes to API calls, docstrings, and parameter usage. (#2197)
  • Allow integration tests configured with xfail_network_error: true to xfail on network errors. (#2199)
  • Address security issues reported by GitHub scanner (https://github.com/gammasim/simtools/security/code-scanning). (#2209)
  • Update simtools-run-application and avoid generation of spurious directory named output. (#2217)
  • Efficiency improvements for unit tests (mostly in unit tests of the plotting routines). (#2223)
  • Minor refactoring of unit tests to clearly follow general rules (e.g., outlined in documentation or skills). (#2226)
  • Improve efficiency of integration tests. (#2227)
