ADC_Keywords: Radio sources ; Polarization Keywords: galaxies: evolution - galaxies: individual (ELAIS N1) - polarization - radio continuum: galaxies - techniques: polarimetric Abstract: We present deep polarimetric observations at 1420MHz of the European Large Area ISO Survey North 1 region (ELAIS N1) as part of the Dominion Radio Astrophysical Observatory Planck Deep Fields project. By combining closely spaced aperture synthesis fields, we image a region of 7.43deg2 to a maximum sensitivity in Stokes Q and U of 78uJy/beam, and detect 786 compact sources in Stokes I. Of these, 83 exhibit polarized emission. Description: Observations for the DRAO ELAIS N1 survey began in 2004 August and will continue to create a final mosaic of 30 fields. This paper presents 21cm continuum polarimetry of the first 10 fields. File Summary:
