[33.01] The Two Micron All Sky Survey

M.F. Skrutskie (University of Massachusetts)

The Two Micron All Sky Survey has imaged 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 located at Mt. Hopkins, Arizona and Cerro Tololo, Chile. The 7.8 seconds of integration time accumulated for each 2" pixel on the sky has yielded a 10-sigma detection level of better than 15.8, 15.1, and 14.3 mag. at J, H, and Ks-bands respectively. 2MASS final data products will include an image atlas with 1" pixels (spatially resampled from 6 independent 1.3s observations), 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. During its observational lifetime the 2MASS project observed 100% of the celestial sphere at release catalog quality or better. The 24 terabytes of raw data have been processed at IPAC with a preliminary version of the 2MASS processing pipeline which evolved during survey operations. 48% of the celestial sphere has been released into the public domain from this initial processing of the data. The Infrared Science Archive (IRSA -- http://irsa.ipac.caltech.edu) at IPAC serves these release products.

The final processing pipeline is now complete and the entire survey raw database will be reprocessed to produce final uniform catalog products and images. This talk will review the anticipated quality and character of the full-sky database now being processed for release in late 2002.

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.
