- Runs: 17478 - 17483
- ELOG link:[ http://www.lst1.iac.es/elog/LST+commissioning/3377]
- Important comments: first run (17478) performed with wrong coordinates. second run (17479) was interrupted to synchronize with Magic
- Observations:
- 2024-05-28 (1.6 h)
'2024-05-28': [17479, 17480 17481 17482 17483] 1.23h
- Data quality selection applied on above data sample: All cut because of NSB, analysis stil done. Run 17479 not included in theta2 because <5 min according to script
- Joint observations with MAGIC? : No
