Deeprange is a contiguous 16 square degree area in the I-band conducted in the mid-90s, using the 2K prime focus CCD camera on the KPNO Mayall 4-m telescope. It was conducted in an effort to improve understanding of the evolution of large-scale structure. It was the first of a new generation of deep, wide-area imaging surveys to study structure at high redshift. The aim was to use the faint galaxies and distant galaxy clusters within this survey to probe large-scale structure evolution over 0 < z < 1. Data products include the reduced and calibrated survey images, an object catalogue, and a galaxy cluster catalogue.
