S) Apertif DR1 - Field calibrated visibilities

This service queries the calibrated 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 Imaging Survey Overview while the area covered by the DR1 can be found Apertif DR1 dataproducts description. In this service query provides for each field the calibrated visibilities in UVFITS format. The frequency range covered by these datasets is 150 MHz and the frequency resolution is 12.2 kHz and the central frequency is 1361.25 MHz. Please find more details in the Apertif DR1 documentation.
