The Legacy Surveys
The Legacy Surveys are producing an inference model catalog of the sky from a set of optical and infrared imaging data, comprising 14,000 deg² of extragalactic sky visible from the northern hemisphere in three optical bands (\(g,r,z\)) and four infrared bands. The sky coverage is approximately bounded by -18° < δ < +84° in celestial coordinates and \(|b|\) > 18° in Galactic coordinates. To achieve this goal, the Legacy Surveys are conducting 3 imaging projects on different telescopes, described in more depth at the following links:
|The Beijing-Arizona Sky Survey (BASS)||The DECam Legacy Survey (DECaLS)||The Mayall z-band Legacy Survey (MzLS)|
