Observation simulator for DL2-level IACT data, originally focused on CTA/LST1 telescope. Simulator uses the specified Monte Carlo simulation files to generate the mock event lists, corresponding to the indicated cosmic sources. Several observational setups are supported (the so-called "wobble", "on" modes), with the mock data optionally split into "observational runs" - similar to those of the real telescope. Cosmic ray sources may be simulated following the analytical spatial / spectral models (several optional are supported) or the FITS cube, defining the spectrum and morphology simultaneously.
Clone and install with pip:
git clone https://github.com/cta-observatory/srcsim.git
cd srcsim
pip install .
There are two main executables to call:
getruns: generates the observational run specifications following the specified configuration file.simrun: performs the simulation for the specified run configuration file.
The example of the configuration file for getruns may be found in the examples directory. When run as getruns --config examples/sim_in_box.yaml it will create configuration files for the separate runs in the out directory (needs to be created). This configuration files can be then processed with simrun one by one.
Please use issues to report problems or make suggestions.
Despite the initial focus on CTA/LST1, the project may be extended to other instruments using the DL2 data format (e.g. other CTA instruments).
Contributions are welcome.
Original developers are Ievgen Vovk, Marcel Strzys and Elise Lagarde.
Active development, so major changes are possible without a notice.
