Data-taking information

• 2024-02-28:
  • Date (time of observation h): 1.3h
    • ZD range (deg): ~50-30 deg
    • Observations:

2024-02-28: [17479, 17480, 17481, 17482, 17483]

• 2024-02-29:
  • Date (time of observation h):
    • ZD range (deg): ~60-35 deg
    • Observations:

2024-05-29: [17507, 17508, 17509, 17510, 17511, 17512, 17513, 17514]

• Data quality selection:

No data quality selection. run 17478 is not used because the wobble is to far from the source.

• Joint observations with MAGIC?:

No (?)

• Information on data-taking (observations summaries): Write here if there was any problem with data-taking.

Moon observations. Moderate-zenith and High-zenith observations.

General analysis information

• source-independent analysis
• lstchain version: v0.10.7
• DL1b processed using tighter image cleaning values. Picture threshold = 14, boundary threshold = 7. These values are used to match the cuts in the MC files (see below). However, they are close to the image cleaning values required for these moon runs.

Monte Carlo information

Write below the MC production ID among the existing MC

• All-sky MC production used: (e.g. 20240229_dec34_nsb14)
• Declination line (training): dec_34.76
