=========================================================================== COSMOS VLA Data Version 1.0 =========================================================================== The Cosmic Evolution Survey (COSMOS) is an HST Treasury Project to survey a 2 square degree equatorial field, centered on RA=10:00:28.6 and DEC=+02:12:21.0, using the ACS camera. The project also incorporates major commitments from other observatories around the world, including the VLA radio telescope. These VLA data represent a pilot program in which a 1-degree diameter circular region at the center of the field was surveyed for 10 hours at 1.4 GHz (20 cm), using the VLA A-array. This survey is a precursor to a complete VLA survey of the entire field, being obtained in 2004 and 2005. The complete survey will use the A- and C-arrays to obtain a sensitivity of 10 uJy/beam. The key characteristics of these data: Configuration: VLA A-array Dates of observations: August, 2003 Observing time: 10 hours Frequency: 1.4 GHz ( = L band, 20cm) Bandwidth: 75 MHz (Multi-channel continuum mode) Pointings: 7 (hexagonal pattern) Area: ~0.84 sq degs (Diameter ~ 1 degree) Resolution: 1.9" x 1.6"; beam PA -23 degrees Sensitivity: 25-100 uJy/beam (inner to outermost regions) The data products available here include: (1) a flux calibrated, astrometrically correct image, in SIN projection [".fits" file] (2) a flux calibrated, astrometrically correct image, in TAN projection ["_tan.fits" file] (3) a point source catalog, containing 246 sources, with their position, fluxes, and sizes [ catalog is located in http://irsa.ipac.caltech.edu/data/COSMOS/tables/ ] Further information may be obtained from the VLA-COSMOS web page: http://www.mpia-hd.mpg.de/homes/schinner/cosmos/cosmos.html or the main COSMOS web page: http://cosmos.astro.caltech.edu/ =========================================================================== January 3, 2004 pls@astro.caltech.edu
