The observations were carried out as part of the Multiwavelength Survey by Yale-Chile (MUSYC) with ISPI on the CTIO 4m telescope. The typical point-source limiting depths are J∼22.5, H∼21.5, and K∼21 (5σ; Vega). The effective seeing in the final images is 1.0". We combine these data with MUSYC UBVRIz imaging to create K-selected catalogs that are unique for their uniform size, depth, filter coverage, and image quality. Description: Observation were performed over the course of nine observing runs from 2003 January to 2006 April. File Summary:
