General information[edit]
- Name of the source: GRB240811A
- Brief description of the source:
- Object type : GRB
- Redshift (z) : ?
- Other relevant information
- RA, Dec in deg (ICRS): 226.3622, 28.8957
- Analysis by:
- Ryuji Takeishi (ICRR - take@icrr.u-tokyo.ac.jp)
Data-taking information[edit]
- Dates of data-taking: 2024-08-11
- ZD range (deg): --> 30-50 deg
- AZ range (deg): -->
- Transmission9km:
- Observation condition: moon
- Observation mode: std wobbles
- Observations:
'2024-08-11': [18574, 18575, 18576, 18577, 18578] 1.84 h
- Data quality selection: Almost runs did not survive the default dR/dI@442pe limit of 1.5. Likely due to high dust concentration. Since almost runs exceed dark NSB limit, we did both analyses with dark NSB MC and high NSB image cleaning MC.
- Joint observations with MAGIC? : yes
- Information on data-taking (observations summaries): https://www.lst1.iac.es/datacheck/observation_overview/2024/08/run_summary_2024_08_11.pdf
General analysis information[edit]
- source-independent analysis
- lstchain version: v0.10.11
