2MASS All-Sky Data Release
Publish Time:2022-04-18
The 2MASS All-Sky Data Release contains highly uniform near infrared Catalog and Image data covering 99.998% of the sky derived from observations made by the Survey's 1.3 m telescopes on Mt. Hopkins, Arizona and Cerro Tololo, Chile. The All-Sky Release data products include a Point Source Catalog (PSC) containing positions and photometry for 470,992,970 objects, a Scan Information Table (SCN) containing information common to the 59,731 Survey scans, an Extended Source Catalog (XSC) containing positions, photometry, and basic shape information for 1,647,599 spatially extended sources, most of which are galaxies, and an Image Atlas containing over 4,121,439 J, H, and Ks FITS images covering the sky. This mirror data set contains the Point Source Catalog, the Scan Information Table, and the Extended Source Catalog. The Atlas Images are not contained here, but are available via on-line the services of the Infrared Science Archive. Other details are in the readme files under the data download link.
