General talk on the LST1 DL3 Tools by Chaitanya Priyadarshi: [https://indico.cta-observatory.org/event/3501/contributions/29581/attachments/19810/27478/DL3_Tools_and_Spectral_analysis_of_Crab_data_with_gammapy.pdf DL3_Tools_and_Spectral_analysis_of_Crab_data_with_gammapy.pdf]
 +
 +
=== DL2toDL3 Tools ===
 +
 +
Tools are located in [https://github.com/cta-observatory/cta-lstchain/tree/master/lstchain/tools lstchain/tools]:
 +
* <font style="color: blue"> lstchain_create_irf_file</font>: create IRFs from the MC file
 +
** The IRFs can be generated using only the gamma MC file, to produce Effective Area, Energy Dispersion <br/>(and PSF for Full Enclosure IRFs, ie. without any theta cuts).
 +
** Proton and Electron MC are used to create the Background IRF.
 +
** For creating point-like IRFs, you have to pass <br>the --point-like flag in the command-line, as by default the Tools generates a Full Enclosure IRF.
 +
* <font style="color: blue"> lstchain_create_dl3_file</font>: create DL3 files
 +
* <font style="color: blue"> lstchain_create_dl3_index_files</font>: generate HDU and OBS Index files of the DL3 files created. <br/>The DL3 files are indexed as per [https://gamma-astro-data-formats.readthedocs.io/en/latest/ GADF] and using [https://cta-observatory.github.io/ctapipe/ctapipe_api/tools/index.html ctapipe tools]
 +
 +
Command options can be checked: lstchain_create_irf_file --help-all
 +
 +
=== DL2 Cuts ===
 +
Fixed cut variables & default values (see [https://github.com/cta-observatory/cta-lstchain/blob/master/lstchain/io/event_selection.py here])
 +
* fixed_gh_cut [0.6]
 +
* fixed_theta_cut [0.2]
 +
* allowed_tels [1]
 +
 +
Cut Methods:
 +
# '''--fixed-gh-cut 0.9'''
 +
# '''--config /path/to/config.json''' <br/>Example json config files for the DL3 tools are [https://github.com/cta-observatory/cta-lstchain/blob/master/docs/examples here] <br/> The DL3 JSON config file ([https://github.com/cta-observatory/cta-lstchain/blob/master/docs/examples/dl3_tool_config.json dl3_tool_config.json]) is a subset of the IRF config file ([https://github.com/cta-observatory/cta-lstchain/blob/master/docs/examples/irf_tool_config.json irf_tool_config.json]). <br/>One can '''use the IRF config file for both tools''' to ensure that the same filter cuts for both MC and real data are used.
 +
 +
'''NOTE''': the fixed_theta_cut option is not available in lstchain_create_dl3_file, so it is better to use the JSON option to be consistent with the IRF generation

Location of LST1 data at La Palma[edit]

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

DL2toDL3 conversion[edit]

General talk on the LST1 DL3 Tools by Chaitanya Priyadarshi: DL3_Tools_and_Spectral_analysis_of_Crab_data_with_gammapy.pdf

DL2toDL3 Tools[edit]

Tools are located in lstchain/tools:

  • lstchain_create_irf_file: create IRFs from the MC file
    • The IRFs can be generated using only the gamma MC file, to produce Effective Area, Energy Dispersion
      (and PSF for Full Enclosure IRFs, ie. without any theta cuts).
    • Proton and Electron MC are used to create the Background IRF.
    • For creating point-like IRFs, you have to pass
      the --point-like flag in the command-line, as by default the Tools generates a Full Enclosure IRF.
  • lstchain_create_dl3_file: create DL3 files
  • lstchain_create_dl3_index_files: generate HDU and OBS Index files of the DL3 files created.
    The DL3 files are indexed as per GADF and using ctapipe tools

Command options can be checked: lstchain_create_irf_file --help-all

DL2 Cuts[edit]

Fixed cut variables & default values (see here)

  • fixed_gh_cut [0.6]
  • fixed_theta_cut [0.2]
  • allowed_tels [1]

Cut Methods:

  1. --fixed-gh-cut 0.9
  2. --config /path/to/config.json
    Example json config files for the DL3 tools are here
    The DL3 JSON config file (dl3_tool_config.json) is a subset of the IRF config file (irf_tool_config.json).
    One can use the IRF config file for both tools to ensure that the same filter cuts for both MC and real data are used.

NOTE: the fixed_theta_cut option is not available in lstchain_create_dl3_file, so it is better to use the JSON option to be consistent with the IRF generation

Example DL2toDL3 commands[edit]

lstchain_create_irf_files
        -g /path/to/DL2_MC_gamma_file.h5
        -o /path/to/irf.fits.gz
        --point-like (Only for point_like IRFs)
        --fixed-gh-cut 0.9
        --fixed-theta-cut 0.2
        --irf-obs-time 50

lstchain_create_dl3_file
        -d /path/to/DL2_data_file.h5
        -o /path/to/DL3/file/
        --input-irf /path/to/irf.fits.gz
        --source-name Crab
        --source-ra 83.633deg
        --source-dec 22.01deg
        --fixed-gh-cut 0.9

lstchain_create_dl3_index_files
        -d /path/to/DL3/files/
        -o /path/to/DL3/index/files
        -p dl3*[run_1-run_n]*.fits.gz

Data is in the tables:

  • 'dl1/event/telescope/parameters/LST_LSTCam' (Hillas parameters, timestamps, pointing, etc)

In case of DL2 only the table parameters 'dl2/event/telescope/parameters/LST_LSTCam' are available, which is a copy of the DL1 table with the reconstructed parameters added

for each of the 53000 events, a calibrated image of the camera is obtained (array of 1855 pixels)

The rest of the tables in the files are metadata (info about the camera, optics, calibration, etc)

Software tool installation[edit]

LSTCHAIN[edit]

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[edit]

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

Convert example jupyter notebook to python[edit]

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:
