Spitzer First Look Survey -- Ancillary VLA Data
Mosaic of 35 VLA pointings
taken during 2001 and 2002, representing 240
hours in B-array at 1.4 GHz. The image is fully
calibrated and corrected for primary-beam
attenuation and sky-curvature distortion. The
data have been convolved with a Gaussian to
yield a 5.0 arcsec FWHM circular beam. The
average rms noise is about 23 microJy/beam. The
pixel size is 1.5 arcsec.

The hundred brightest
extracted radio components (with peak
intensities ranging from 221 to 5.6
milliJy/beam) are also shown, with the symbols
scaled by peak intensity.
The Spitzer First Look Survey (FLS) is the
initial Director's Discretionary Time program
executed on the observatory. The extragalactic
component is composed of 4 square degrees of
imaging with MIPS and IRAC centered at
J1718+5930. We have obtained data with the
VLA of this field. Available to the
public is a catalog of radio sources along with
a mosaic of 35 VLA pointings taken during 2001
and 2002, representing 240 hours in B-array at
1.4 GHz. The FLS data coverage is represented
in the VLA image with overlays above. The
brightest point source information is shown in
yellow.

Cutouts Service, which is a general tool to create single or multiple small FITS
(and JPEGs) image cutouts of datasets archived at IRSA.
