validate_camera_efficiency#

Summary#

This application validate the camera efficiency by simulating it using the testeff program provided by sim_telarray.

The results of camera efficiency for Cherenkov (left) and NSB light (right) as a function of wavelength are plotted. See examples below.

Command line arguments#

site (str, required)

North or South.

telescope (str, required)

Telescope model name (e.g. LST-1, SST-D, …)

model_version (str, optional)

Model version (default=’Released’)

zenith_angle (float, optional)

Zenith angle in degrees (between 0 and 180).

azimuth_angle (float, optional)

Telescope pointing direction in azimuth. It can be in degrees between 0 and 360 or one of north, south, east or west (case insensitive). Note that North is 0 degrees and the azimuth grows clockwise, so East is 90 degrees.

nsb_spectrum (str, optional)

File with NSB spectrum to use for the efficiency simulation. The expected format is two columns with wavelength in nm and NSB flux with the units: [1e9 * ph/m2/s/sr/nm]. If the file has more than two columns, the first and third are used, and the second is ignored (native sim_telarray behaviour).

verbosity (str, optional)

Log level to print

Example#

MST-NectarCam - Prod5

Runtime < 1 min.

simtools-validate-camera-efficiency --site North \
    --azimuth_angle 0 --zenith_angle 20 \
    --nsb_spectrum average_nsb_spectrum_CTAO-N_ze20_az0.txt \
    --telescope MST-NectarCam-D --model_version prod5

The output is saved in simtools-output/validate_camera_efficiency.

Expected final print-out message:

INFO::validate_camera_efficiency(l118)::main::Plotted NSB efficiency in /workdir/external/        simtools/simtools-output/validate_camera_efficiency/application-plots/validate_camera        _efficiency_MST-NectarCam-D_nsb
