Data Products

Argus Array data will be freely available to the community and distributed publicly in near real-time as a variety of pre-defined data products designed to meet the needs of a broad range of science cases. Full-sky Argus data accumulates at petabytes-per-night rates and is only stored long enough to produce long-term data products, including full-sky coadds and full-cadence imaging for selected fields.
