Description:
The Two Micron All Sky Survey (2MASS) project is designed to close the
gap between our current technical capability and our knowledge of the
near-infrared sky. In addition to providing a context for the
interpretation of results obtained at infrared and other wavelengths,
2MASS will provide direct answers to immediate questions on the
large-scale structure of the Milky Way and the Local Universe.
To achieve these goals, 2MASS is uniformly scanning the entire sky in
three near-infrared bands to detect and characterize point sources
brighter than about 1 mJy in each band, with signal-to-noise ratio
(SNR) greater than 10, using a pixel size of 2.0". This will achieve
an 80,000-fold improvement in sensitivity relative to earlier surveys.
2MASS uses two new, highly-automated 1.3-m telescopes, one at Mt.
Hopkins, AZ, and one at CTIO, Chile. Each telescope is equipped with a
three-channel camera, each channel consisting of a 256x256 array of
HgCdTe detectors, capable of observing the sky simultaneously at J
(1.25 mum), H (1.65 mum), and Ks (2.17 mum), to a 3sigma
limiting sensitivity of 17.1, 16.4 and 15.3mag in the three bands.
The 2MASS arrays image the sky while the telescopes scan smoothly in
declination at a rate of 1' per second. The 2MASS data "tiles" are 6
deg. long in the declination direction and one camera frame (8.5')
wide. The camera field-of-view shifts by 1/6 of a frame in
declination from frame-to-frame. The camera images each point on the
sky six times for a total integration time of 7.8 s, with sub-pixel
"dithering", which improves the ultimate spatial resolution of the
final Atlas Images.
The University of Massachusetts (UMass) is responsible for the overall
management of the project, and for developing the infrared cameras and
on-site computing systems at both facilities. The Infrared Processing
and Analysis Center (IPAC) is responsible for all data processing
through the Production Pipeline, and construction and distribution of
the data products. The 2MASS project involves the participation of
members of the Science Team from several different institutions. The
2MASS project is funding by the National Aeronautics and Space
Administration (NASA) and the National Science Foundation (NSF).
