Data Analysis
- Data Search & Quality Check
- based on Abelardo's notebook, as of Dec 2022. 212 Runs (50.0 hr) found.
- 171 runs (41.6 hr) survived the notebook. Additionally, 6 runs were removed, judging from the size distribution.
- ToDo: systematic check of the size distribution, introduce the Zd dependence.
- Will be updated (as of Nov 2023)
- Used Data
- Observation Data
- paths: /fefs/aswg/data/real/DL1/*/v0.9/tailcut84/dl1_LST-1.Run*.h5
- MC
- To use the diffuse MCs both for testing/training, we manually split the Training MCs.
- split ratio (train/test): 50/50 for Gamma, 80/20 for Proton
- paths: /fefs/aswg/data/mc/DL1/AllSky/20221027_v0.9.9_base_prod/TrainingDataset/dec_min_2924/GammaDiffuse
- Observation Data
- Analysis Pipilines
- lstchain v0.9.9
- pybkgmodel
- gammapy v0.20.1
- Random Forest
- We train RFs on the node-by-node basis
- keys: "x", "y" were removed for the FoV stability, "sin_az_tel", "alt_tel" were removed for node-by-node RFs
