Data-taking information[edit]

  • Dates of data-taking: 2024-10-29
    • Date (time of observation h) 2024-10-29: 1.488 h
      • ZD range (deg): 22-42
      • Observations: (see example below)
2024-10-29: [19377 19378 19379 19381 19382]
  • Data quality selection: 19376, 19380 runs did not survive the data quality selection (max NSB std: 2.3)

Cross-check[edit]

  • Dates of data-taking: 2024-10-29
    • Date (time of observation h) 2024-10-29: 1.27 h
