VERITAS DL3 Event Data: Release v0.1 - Test Data Set

The Very Energetic Radiation Imaging Telescope Array System (VERITAS; [1]) is a ground-based gamma-ray instrument at the Fred Lawrence Whipple Observatory in southern Arizona, USA. Comprising four 12m optical reflectors, VERITAS operates in the GeV-TeV energy range, with peak sensitivity between 100 GeV and 10 TeV.

This repository contains high-level data products from VERITAS observations (2007-2024). The data includes event lists and instrument response functions processed using the Eventdisplay [2] package for calibration and reconstruction. Event lists support both point-like and full-enclosure analyses with five gamma-hadron separation cuts. Data follows the Gamma-ray Astronomy Data Format (GADF; [3]) and is compatible with open-source tools like gammapy [4].

Access is currently restricted to VERITAS collaboration members, with future open access under discussion. Members should contact repository conveners for access.

This is a test-release (v0.1) with data products not intended for scientific publication.
