First version of new simulation model repository include prod5 and prod6 values
New structure of simulation model repository with values and files copied from https://gitlab.cta-observatory.org/cta-science/simulations/simulation-model/model_parameters.
Main changes are
- versioning of model parameters
- introduction of production tables
Notes:
- gitlab-CI file is not tested yet (awaits a new container image from simtools).
- temporary scripts used to copy over files from model parameter repository are in simulation-models/tmp_scripts/. Assumption is that we don't want to keep them, but they are probably valuable until this version is in production status.
