Scientific paper

The First-Look Survey (FLS) of the Space Infrared Telescope Facility (SIRTF) will cover about 5 deg2 centered on J2000.0 α=17h18m, δ=+59°30' in order to characterize the extragalactic infrared sky 2 orders of magnitude deeper than the IRAS survey. We expect that most of the FLS far-infrared (λ=160, 70, and 24 μm) sources will be star-forming galaxies obeying the very tight far-infrared/radio correlation and will be continuum radio sources with flux densities S>~100 μJy at ν=1.4 GHz. Conversely, radio sources stronger than 100 μJy are usually powered by star-forming galaxies, plus some active galactic nuclei, and most should be detectable by the SIRTF FLS. Thus, a sensitive radio survey can be used to select and identify most of the SIRTF FLS source population before launch. We used the B configuration of the VLA to make an image of the FLS area at ν=1.4 GHz with σ~23 μJy beam-1 rms fluctuations, θ=5.0" resolution, and σα~σδ<~0.5" rms uncertainties in right ascension and declination. The resulting radio image and catalog of 3565 radio components with peak flux densities Sp>=5 σ=115 μJy beam-1 have been released via the Web to expedite follow-up optical identification and spectroscopy.
