LST analysis[edit]

Data-taking information[edit]

  • NSB level: all data was taken in dark NSB conditions
  • Zenith angles: 15-54 deg (December 2023 data have zenith angle > 30 deg)

Good-quality selected dataset[edit]

The list of data runs below was obtained using the latest notebook (https://github.com/cta-observatory/cta-lstchain/blob/main/notebooks/data_quality.ipynb).

Also, short data runs (< 5 min) were excluded, because usually short runs are a symptom of problems during data acquisition. 


'2023-12-09': [15942, 15943, 15944, 15945],
