Description:
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(1.25mum), H(1.65mum),
and Ks(2.16mum) bandpasses. Observations were conducted from two
dedicated 1.3 m diameter telescopes located at Mount Hopkins, Arizona,
and Cerro Tololo, Chile. The 2MASS All-Sky Data Release includes the
FITS images covering the entire sky, a Point Source Catalog (PSC) of
471 million sources (Cat. II/242), and the present Extended Source
Catalog.
The 2MASS Extended Source Catalog contains sources that are extended
with respect to the instantaneous PSF, such as galaxies and Galactic
nebulae. The algorithms used to create the 2MASX catalog are described
by Jarett et al. (2000AJ....119.2498J), and in the 2MASS Explanatory
Supplement (accessible from the 2MASS Home Page). Briefly, point/
extended-source discrimination was conducted for each band-merged
point-source detection by comparing a variety of radial shape, surface
brightness, image moments, and symmetry parameters with characteristic
stellar parameters using an oblique decision tree classifier. The
classification tests included filters to exclude double and triple
stars, which were one of the main contaminants in high source density
regions. Stellar parameters were measured empirically as a function
of time in each scan to compensate for variations in the atmospheric
seeing using the aggregate properties of band-merged point-source
extractions.
The catalog contains 389 columns described briefly in the
"Byte-by-byte Description" section below; their description
includes also the 2MASS database original column names used
in the original descriptions.
