• Analysis by:
  • Juan Bernete (CIEMAT - juan.bernete@ciemat.es)

Data-taking information

• Dates of data-taking:
  • Date: 2024-05-30 (0.739 h)
    • ZD range (deg): 12 - 18
    • Observations:

2024-05-30: [17517, 17518, 17519, 17520]

• Data quality selection: 17517 and 17518 survive the data quality selection, but the analysis is performed with all the runs as they are not so bad.
• Joint observations with MAGIC?: No
• Information on data-taking (observations summaries): Run 17520 was interrupted just after started
