S) Apertif DR1 - Field raw visibilities

This service queries the raw visibilities of the fields of the Apertif DR1 data collection. This data release contains continuum images, HI cubes, polarization cubes and other ancillary data (e.g. raw and calibrated visibilities). The imaging survey is split into two tiers: a wide-shallow tier consisting of a single observation per field and a medium-deep tier consisting of ten observations per field. The imaging survey footprint can be found in the Imaging Survey overview while the area covered by the DR1 can be found in the Apertif DR1 dataproducts description. In this service query provides for each field the raw visibilities in MS format. These are observed at the central frequency of 1280 MHz, covering a bandwidth of 300 MHz and a frequency resolution of 12.2 kHz. Please find more details in Apertif DR1 documentation.
