Import of simulation model parameters

Import simulation model parameters from sim_telarray

The general use case for simtools is to generate sim_telarray configurations using the simulation models databases. This page describes the reverse process, i.e. generating model parameters in the simtools data format from sim_telarray configuration files. This is useful for e.g., for the initial generation of the simulation models database or for verification.

Import Prod6 model parameters

Prod6 model parameters can be extracted from sim_telarray using the following commands.

./sim_telarray/bin/sim_telarray \
   -c sim_telarray/cfg/CTA/CTA-PROD6-LaPalma.cfg \
   -C limits=no-internal -C initlist=no-internal \
   -C list=no-internal -C typelist=no-internal \
   -C maximum_telescopes=30 -DNSB_AUTOSCALE \
   -DNECTARCAM -DHYPER_LAYOUT -DNUM_TELESCOPES=30 \
   /dev/null 2>|/dev/null | grep '(@cfg)'  >| all_telescope_config_la_palma.cfg

./sim_telarray/bin/sim_telarray \
   -c sim_telarray/cfg/CTA/CTA-PROD6-Paranal.cfg \
   -C limits=no-internal -C initlist=no-internal \
   -C list=no-internal -C typelist=no-internal \
   -C maximum_telescopes=87 -DNSB_AUTOSCALE \
   -DNECTARCAM -DHYPER_LAYOUT -DNUM_TELESCOPES=87 \
   /dev/null 2>|/dev/null | grep '(@cfg)'  >| all_telescope_config_paranal.cfg

Import Prod5 model parameters

Prod5 model parameters can be extracted from sim_telarray using the following commands.

./sim_telarray/bin/sim_telarray \
   -c sim_telarray/cfg/CTA/CTA-PROD5-LaPalma.cfg \
   -C limits=no-internal -C initlist=no-internal \
   -C list=no-internal -C typelist=no-internal \
   -C maximum_telescopes=85 -DNSB_AUTOSCALE \
   -DNECTARCAM -DHYPER_LAYOUT -DNUM_TELESCOPES=85 \
   /dev/null 2>|/dev/null | grep '(@cfg)'  >| all_telescope_config_la_palma_prod5.cfg

./sim_telarray/bin/sim_telarray \
   -c sim_telarray/cfg/CTA/CTA-PROD5-Paranal.cfg \
   -C limits=no-internal -C initlist=no-internal \
   -C list=no-internal -C typelist=no-internal \
   -C maximum_telescopes=120 -DNSB_AUTOSCALE \
   -DNECTARCAM -DHYPER_LAYOUT -DNUM_TELESCOPES=120 \
   /dev/null 2>|/dev/null | grep '(@cfg)'  >| all_telescope_config_paranal_prod5.cfg

Import telescope positions

Positions of array elements like telescopes are provided by CTAO in form of tables (typically ecsv files). To import these positions into the model parameter repository, see the following example:

simtools-write-array-element-positions-to-repository \
    --input /path/to/positions.txt \
    --repository_path /path/to/repository \
    --model_version 1.0.0 \
    --coordinate_system ground \
    --site North
