VizieR Online Data Catalog: ATLAS 1.4GHz Data Release 2 (Hales+, 2014)

ATLAS observations of the CDF-S and ELAIS-S1 fields were obtained with the ATCA, a synthesis telescope consisting of six 22m alt-az antennas on an east-west baseline. Each antenna is equipped with linearly polarized feeds used to measure all four polarization products (XX, YY, XY, YX), from which all four Stokes parameters (I, Q, U, V) can be derived. Noise diodes in the feed horns of each antenna replace the need to observe a polarization position angle calibrator to derive absolute XY phase.

We supplemented our 1.4GHz radio observations with data at infrared and optical wavelengths.
