The CFHT Science Archive, hosted by the Canadian Astronomy Data Centre, provides access to observations from the Canada-France-Hawaii Telescope (CFHT) on Maunakea, Hawaii. This dataset contains raw and calibrated science observations, calibrations, and stacked data products from instruments such as MegaPrime, WIRCam, SITELLE, and SPIRou. Queries can be made by object name, position, or RunID. The purpose of the archive is to facilitate retrieval and scientific analysis of CFHT observations, with proprietary data accessible by designated investigators or authorized users after a typical 13-month proprietary period.
