[34.01] What 2MASS Can Do For You

M.F. Skrutskie (University of Massachusetts)

The Two Micron All Sky Survey is imaging the entire celestial sphere in the near-infrared J (1.25um), H (1.65um), and Ks (2.16um) bandpasses from two 1.3-meter telescopes cited at Mt. Hopkins, Arizona and Cerro Tololo, Chile. The 7.8 seconds of integration time accumulated for each 2" pixel on the sky yields a 10-sigma detection level of better than 15.8, 15.1, and 14.3 magnitudes at J, H, and Ks-bands respectively. 2MASS data products will ultimately consist of an all-sky image atlas with 1" pixels (spatially resampled from the 6 consecutive 1.3 second observations of each 2" pixel), a point source catalog containing over 300 million objects, and an extended source catalog containing between 1 and 2 million sources most of which will be galaxies. The Infrared Science Archive (IRSA -- http://irsa.ipac.caltech.edu) at IPAC currently serves the released 2MASS data products. At the time of this presentation the project expects that 45% of the sky, or approximately 20,000 square degrees will be in the public domain. This talk will illustrate the quality and utility of the data in a variety of scientific contexts.

The Two Micron All Sky Survey is a joint project of the University of Massachusetts and the Infrared Processing and Analysis Center and is funded by the National Aeronautics and Space Administration and the National Science Foundation.
