2MASS Six Degree Mosaic Images

The Two Micron All Sky Survey (2MASS) 6° Mosaic Images are a dataset of 6x6 square degree 2MASS mosaics created by the NASA/IPAC Infrared Science Archive (IRSA) 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 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.
This dataset or service is made available by the Infrared Science Archive (IRSA) at IPAC, which is operated by the California Institute of Technology under contract with the National Aeronautics and Space Administration.
