dl1-data-handler 0.14.1

A package of utilities for reading, and applying image processing to Cherenkov Telescope Array (CTA) R1/DL0/DL1 data in a standardized format. Created primarily for testing machine learning image analysis techniques on IACT data.

A package of utilities for reading, and applying image processing to Cherenkov Telescope Array Observatory (CTAO) R1/DL0/DL1 data in a standardized format. Created primarily for testing machine learning image analysis techniques on IACT data.

Currently supports ctapipe v6.0.0 data format.

Previously named image-extractor (v0.1.0 - v0.6.0). Currently under development, intended for internal use only.

Installation

The following installation method (for Linux) is recommended:

Installing as a conda package

To install dl1-data-handler as a conda package, first install Anaconda by following the instructions here: https://www.anaconda.com/distribution/.

The following command will set up a conda virtual environment, add the necessary package channels, and install dl1-data-handler specified version and its dependencies:

DL1DH_VER=0.14.1
wget https://raw.githubusercontent.com/cta-observatory/dl1-data-handler/v$DL1DH_VER/environment.yml
conda env create -n [ENVIRONMENT_NAME] -f environment.yml
conda activate [ENVIRONMENT_NAME]
conda install -c ctlearn-project dl1_data_handler=$DL1DH_VER

This should automatically install all dependencies (NOTE: this may take some time, as by default MKL is included as a dependency of NumPy and it is very large).
