The Swift gamma-ray burst (GRB) observatory was launched in 2004 November, and has been continually observing the hard X-ray (14–195 keV) sky ever since with the Burst Alert Telescope (BAT). The 70 month Swift-BAT survey is the most sensitive and uniform hard X-ray all-sky survey and reaches a flux level of 1.03×10−11 erg s−1cm−2 over 50% of the sky and 1.34×10−11 erg s−1cm−2 over 90% of the sky. Swift has three co-aligned instruments for studying gamma-ray bursts and their afterglow: the Burst Alert Telescope (BAT), the X-ray Telescope (XRT), and the Ultraviolet/Optical Telescope (UVOT).

CADE only serves data obtained with the BAT instrument, in 8 energy bands: 14-20 keV, 20-24 keV, 24-35 keV, 35-50 keV, 50-75 keV, 75-100 keV, 100-150 keV, and 150-195 keV, at an angular resolution of 19.5'. Healpix maps are in units of cnts/s/detector. The detector is an individual piece of CZT in the BAT array with an area of 1.6E-7 m2.
