simtools-generate-simtel-event-data

Generate a reduced dataset of event data from simulated files.

Processes sim_telarray output files (typically of type ‘.simtel.zst’) and creates a reduced dataset containing shower information, array-level parameters, and data about triggered telescopes.

Command line arguments

prefix (str, required)

Path prefix for the input files.

output_file (str, required)

Output file path.

max_files (int, optional, default=100)

Maximum number of input files to process.

print_dataset_information (int, optional, default=0)

Print information about the datasets in the generated reduced event dataset.

Example
