Apertif DR2 - Polarization cubes
Apertif is a phased-array feed system for the Westerbork Synthesis
Radio Telescope (WSRT), providing forty instantaneous beams over 300
MHz of bandwidth. A description of the second data release is to be
included here. This service queries the polarization cubes from the
second data release of Apertif. In order to prevent bandwidth
depolarization and enable rotation measure synthesis studies, Stokes Q
and U cubes with a frequency resolution of 6.25 MHz are produced. The
cubes have a smaller spatial extent of 2.7 deg × 2.7 deg (2049 × 2049
pixels, with 4''/pixel ) than the continuum or Stokes V images but
still extend well beyond the primary beam.
