Apertif DR2 - Polarization calibrator raw visibilities
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. The raw visibility data are provided as separate collections for the survey fields, flux calibrator and polarization calibrator observations.
The tables can be joined to identify the associated calibrators for a target observation. This service queries the raw visibilities for the polarization calibrator. These are stored on tape and are not immediately available for download.
