Two Micron All-sky Survey
(near-infrared survey of both hemispheres)
The Two Micron All-sky Survey is a
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 dwarfs,
low mass stars, and general cataloging.
