Abstract: "Between 1997 June and 2001
February the Two Micron All Sky Survey (2MASS) collected 25.4 Tbytes of raw
imaging data covering 99.998% of the celestial sphere in the near-infrared J
(1.25 mu m), H(1.65 mu m), and Ks(2.16 mu m) bandpasses. Observations were
conducted from two dedicated 1.3 m diameter telescopes located at Mount
Hopkins, Arizona, and Cerro Tololo, Chile. The 7.8 s of integration time
accumulated for each point on the sky and strict quality control yielded a
10 sigma point-source detection level of better than 15.8, 15.1, and 14.3
mag at the J, H, and Ks bands, respectively, for virtually the entire sky.
Bright source extractions have 1 sigma photometric uncertainty of < 0.03 mag
and astrometric accuracy of order 100 mas. Calibration offsets between any
two points in the sky are < 0.02 mag. The 2MASS All-Sky Data Release
includes 4.1 million compressed FITS images covering the entire sky, 471
million source extractions in a Point Source Catalog, and 1.6 million
objects identified as extended in an Extended Source Catalog."
