The Infrared Array Camera (IRAC) shallow survey

The Infrared Array Camera (IRAC) shallow survey covers 8.5 deg(2) in the NOAO Deep Wide-Field Survey in Bootes with three or more 30 s exposures per position. An overview of the survey design, reduction, calibration, star-galaxy separation, and initial results is provided. The survey includes approximate to370,000, 280,000, 38,000, and 34,000 sources brighter than the 5 sigma limits of 6.4, 8.8, 51, and 50 muJy at 3.6, 4.5, 5.8, and 8 mum, respectively, including some with unusual spectral energy distributions.
