Two Micron All-Sky Survey

(near-infrared survey of both hemispheres)

The Two Micron All-Sky Survey is a Near-infrared Survey of the entire sky by two telescopes, in Mt. Hopkins, Arizona and Cerro Tololo, Chile. The sky was imaged in three Bands: J (1.25um), H (1.65um), and K(s)(2.17um), i.e., the JHK Photometric System. Final data was released in 2003.

Targets included galaxies obscured by Milky Way light, Brown Dwarves, Low Mass Stars, and general cataloging.
