Location of LST1 data at PIC

Use CTA observatory LDAP account (monica.vazquez)

Location of LST1 at La Palma

  • Directory: /fefs/onsite/data
    Use cp01/cp02 to copy out data, never the login machine

Run summary info/data-check

DL3 Data

  • DL3 Daniel Morcuende:
    /fefs/aswg/workspace/daniel.morcuende/data/real/DL3/20201120/v0.7.3/tailcut84/
    • dl3_LST-1.RunXXX.fits.gz
    • hdu-index.fits.gz
    • obs-index.fits.gz

Analysis of LST1 data

Donwload LST analysis software cta-lstchain (wrapper that uses centrally supported ctapipe routines) 

git clone https://github.com/cta-observatory/cta-lstchain.git
cd cta-lstchain

LSTCHAIN_VER=0.7.2
wget https://raw.githubusercontent.com/cta-observatory/cta-lstchain/v$LSTCHAIN_VER/environment.yml
conda env create -n lst -f environment.yml
conda activate lst
pip install lstchain==$LSTCHAIN_VER
rm environment.yml

In case of problems with conda env try mamba:
conda install -c conda-forge -n base mamba
mamba env create -f environment.yml

Files needed to analyze golden Run 442 (20190527):

  • Pedestal run: pedestal_file_run446_0000.fits
  • Low level DRS4 calibration: calibration.hdf5

Run directly jupyter notebook

cd cta-lstchain/notebooks
jupyter notebook
-> select Analyze_real_muon_data.ipynb

Convert example jupyter notebook to python

cd cta-lstchain/notebooks
jupyter nbconvert --to python Analyze_real_muon_data.ipynb

Fix path of data, pedestal and calibration and run! 

Lines to fix:
source = event_source(input_url="../data/LST-1.4.Run00442.0001.fits.fz",max_events=None)
pedestal_path="../pedestal/pedestal_file_run446_0000.fits",
with HDF5TableReader('../calibration/calibration.hdf5') as h5_table:

python Analyze_real_muon_data.py

LST1 data formats

El contenido de los ficheros se puede ver con:

De ahí, los datos como tal están en las tablas 'dl1/event/telescope/image/LST_LSTCam' (imágenes calibradas de la cámara) y 'dl1/event/telescope/parameters/LST_LSTCam' (parámetros de Hillas, timestamps, pointing, etc) En el caso de dl2 solamente se tiene la tabla de parámetros 'dl2/event/telescope/parameters/LST_LSTCam' , que es una copia de la tabla dl1 con los parámetros reconstruidos añadidos.

Para acceder a la tabla de parámetros tanto en dl1 como en dl2: 

dl2_dataframe = pd.read_hdf(file, key=dl2_params_lstcam_key)

Acceder a las imágenes es algo más complicado y requiere el módulo tables 

from astropy.table import Table
images = Table.read(dl1_file, path=dl1_images_lstcam_key)['image']
images

para cada uno de los 53000 eventos, se tiene una imagen calibrada de la cámara (array de 1855 pixels)

el resto de tablas en los ficheros son metadatos (info sobre cámara, óptica, calibración, etc)
