A SCUBA Map in the Spitzer First Look Survey: Source Catalog and Number Counts

Abstract

Using the SCUBA instrument on the JCMT, we have made a submillimeter mosaic at 850um of a subarea of the Spitzer First Look Survey (FLS). Our image covers the central 151 square arcmin of the northern extragalactic Continuous Viewing Zone (CVZ) field of the FLS to a median 3sigma depth of 9.7 mJy. The image contains ten 850um sources detected at 3.5sigma or higher significance, of which five are detected at greater than or equal 4sigma. We make the catalog of these SCUBA-selected FLS sources available to the community. After correcting for incompleteness and flux bias, we find that the density of sources brighter that 10mJy in our field is (1.3 +1.1 -0.7)x10^2 deg^-2 (95% Poisson confidence limits), which is consistent with other surveys that probe the bright end of the submillimeter population.
