Apertif DR2 - Polarization cubes
Listed in IVOA Registry (Virtual Observatory)
Apertif is a phased-array feed system for the Westerbork Synthesis Radio Telescope (WSRT), providing forty instantaneous beams over 300 MHz of bandwidth.
Description
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.
