Background
DataArchives

Most modern telescopes maintain a publicly accessible archive of data. We recommend checking for existing observations before applying to use any of these telescope. Here we list the known open archives for ITSO-supported facilities:

Gemini

Keck

Blanco/DECam

  • The Blanco telescope DECam data is hosted on the NOAO Science Archive. The Dark Energy Survey (DES) DES-Y1 data release consists of science observations taken between September 2013 and early February 2014, while the DECam Legacy Survey (DECaLS) third data release (DR3) consists of science observations taken mainly between August 2014 and March 2016.

Magellan

  • There are currently no public archives for Magellan telescope data.

Subaru

ESO

  • The ESO Science Archive Facility contains data from ESO telescopes at La Silla Paranal Observatory, including the APEX submillimeter telescope on Llano de Chajnantor. In addition, the raw UKIDSS/WFCAM data obtained at the UK Infrared Telescope facility in Hawaii are available.
  • To search and to request raw observational data taken by telescopes of the La Silla Paranal Observatory use the Observational Raw Data Query Form.
