Data-taking information[edit]
- Dates of data-taking: 2024-06-07
- ZD range (deg): --> 25 - 40 deg
- AZ range (deg): -->
- Transmission9km:
- Observation condition: dark
- Observation mode: std wobbles
- Runs: 17676 - 17681
- Observations:
'2024-06-07': [17676, 17677, 17678, 17679, 17680, 17681] h
- Data quality selection applied on above data sample: all data passes, just 17678 < 1 min, so not taken into account
- Joint observations with MAGIC? : From 17679 on
