Select good quality data

Run notebook:
/home/monica.vazquez/LST1SCHOOL2024/notebooks/data_quality.ipynb

data_quality notebook settings to select crab data taken in the night 2023/01/17:

files = glob.glob("/fefs/aswg/data/real/OSA/DL1DataCheck_LongTerm/v0.10/2023????/DL1_datacheck_2023*.h5")
source_coordinates = SkyCoord.from_name("Crab Nebula")
max_zenith = 35 * u.deg
first_date = 20230117
last_date  = 20230117

To check the most recent version of all the data use this location:

/fefs/aswg/data/real/OSA/DL1DataCheck_LongTerm/night_wise/all/

IRF creation

Use the test MC of the same declination line used in the DL2 step

cd /home/monica.vazquez/LST1SCHOOL2024/helpful_scripts
cp /fefs/aswg/workspace/analysis-school-2024/cta-lstchain/docs/examples/irf_tool_config.json .

The default json has energy dependent gammaness and theta containment cuts of 70%
