Dataset Summary
This is a mirror of the Open Crab Sample released by the FACT collaboration, containing simulations of astroparticle events as seen by the FACT telescope from the CORSIKA simulation program, as well as a few nights of observations of the Crab Nebula over 2013 and 2014. The simulation data is in two formats, the photon stream format, as well as a preprocessed version containing extracted features, and cleaned point clouds, which were performed with various levels of DBSCAN. The observations are all the raw data, with no cleaning or extracted features.
Supported Tasks and Leaderboards
- 'classification': Classification of simulated events as either hadron or gamma events.
- 'regression': Predicting the energy of the initial energy of the simulated events, or where in the night sky the original particle originated

Dataset Creation
Curation Rationale
The goal of the Open Crab Sample is to open up astroparticle data for exploring different ways of doing analysis.
Source Data
Initial Data Collection and Normalization
The initial simulated data was generated by the CORSIKA simulation program. The observations were taken by the FACT telescope on La Palma between 2013 and 2014. The data is not normalized.

Annotations
Annotation process
The simulations were annotated from the ground truth in the simulation, while the observations have no ground truths.
