A SCUBA MAP IN THE SPITZER FIRST LOOK SURVEY: SOURCE CATALOG AND NUMBER COUNTS

摘要

Using the Submillimetre Common-User Bolometer Array (SCUBA) instrument on the James Clerk Maxwell Telescope, we have made a submillimeter mosaic at 850 μm of a subarea of the Spitzer First Look Survey (FLS). Our image covers the central 151 arcmin~2 of the northern extragalactic continuous viewing zone field of the FLS to a median 3 σ depth of 8.4 mJy. The image contains six 850 μm sources detected at 3.0 σ or higher significance. 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 than 7 mJy in our field is 2.2_(-1.0)~(+2.5) x 10~2 deg~(-2) (95% Poisson confidence limits), which is consistent with other surveys that probe the bright end of the submillimeter population.
