## Description

Legacy Survey is a well-known brand that specializes in providing a comprehensive and accurate model of the extragalactic sky in the optical and infrared domains. This brand is recognized for its Legacy Surveys, namely MzLS, DECaLS, and BASS, which have conducted dedicated observations covering approximately 14,000 square degrees of the extragalactic sky visible from the northern hemisphere. These surveys capture data in three optical bands (g, r, z) and are further enhanced with four infrared bands from NEOWISE. To expand their self-consistent inference model, Legacy Survey is incorporating additional public DECam data from the NOIRLab Data Archive, covering over 20,000 square degrees in extra optical bands (g, r, i, z). The brand's offerings also include the Beijing-Arizona Sky Survey (BASS), the DECam Legacy Survey (DECaLS), and the Mayall z-band Legacy Survey (MzLS). Users can access an interactive map and data viewer to explore the vast array of information provided by the brand. Legacy Survey is supported by the U.S. Department of Energy, NSF's NOIRLab, and various other renowned institutions, ensuring the accuracy and quality of their services.
