simtools-simulate-pedestals#

Simulate pedestal events.

Use sim_telarray to simulate pedestal events for an array of telescopes. The following types are supported:

  • Pedestal events (includes night-sky background and camera noise)

  • Dark pedestal events (closed camera lid, camera noise only)

  • NSB-only pedestal events (open camera lid, night-sky background only, no camera noise)

Example#

Simulate pedestal events for Alpha North. The assumed level night-sky background is 2.0 times the nominal value. A list of stars can be provided to simulate additional contributions.

simtools-simulate-pedestals --run_mode=pedestals \\
    --run_number 10 --number_of_events 1000 \\
    --array_layout_name alpha --site North \\
    --model_version 6.0.0 \\
    --zenith_angle 20 --azimuth_angle 0 \\
    --nsb_scaling_factor 2.0

Command Line Arguments#

run_mode (str, required)

Run mode, e.g. “pedestals”

run_number (int, required)

Run number for the simulation.

number_of_events (int, required)

Number of calibration events to simulate.

array_layout_name (str, required)

Array layout name, e.g. “alpha”.

site (str, required)

Site name.

model_version (str, optional)

Version of the simulation model.

nsb_scaling_factor (float, optional)

Scaling factor for the night-sky background rate. Default is 1.0, which corresponds to the nominal (dark sky) NSB rate.

stars (str, optional)

Path to a file containing a list of stars (azimuth, zenith, weighting factor separated by whitespace). If provided, the stars will be used to simulate additional contributions to the night-sky background. For details on the parameters, see the sim_telarray manual.

zenith_angle (float, optional)

Zenith angle in degrees.

azimuth_angle (float, optional)

Azimuth angle in degrees.

simulate_pedestals.main()[source]#
