The Wide-field Infrared Survey Explorer (WISE) is a space-based imaging
survey of the entire sky in the 3.4 (W1), 4.6 (W2), 12 (W3), and 22 (W4) μm
mid-infrared. This is the project's reliable Source Catalog containing
accurate photometry and astrometry for over 500 million objects.
More details are available in the `Explanatory Supplement`_, which also
has a list of `Cautionary Notes`_.
