2MASS Six Degree Mosaics
Listed in IVOA Registry (Virtual Observatory)
The Two Micron All Sky Survey (2MASS; Skrutskie et al. 2006, AJ 131, 1163) was a survey of the entire sky in three infrared wavebands: J (1.235 microns), H (1.662 microns), and KS (2.159 microns).
Description
The 2MASS All-Sky Data Release products include 4,121,439 Atlas Images (512 x 1024 pixels, 1 arcsec/pixel) in the three survey bands. For users wishing to visualize regions of the sky that are significantly larger than the Atlas Images, or that fall close to the edge of an Atlas Image, the NASA/IPAC Infrared Science Archive (IRSA) has created 6 x 6 degree 2MASS mosaics.
The primary set consists of 1,734 mosaics with a 1 arcsecond pixel scale (the same pixel scale as the Atlas Images), resulting in individual files that are 1.9 Gb. Also available are 52 Mb mosaics that have been binned to a 6 arcsecond pixel scale.
