M) Apertif DR1 - HI spectral cubes

This service queries the HI spectral cubes 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, for each observation there are four line sets of cubes of four different frequency ranges (1292.5-1337.1 MHz, 1333.1-1377.7 MHz, 1373.8-1418.4 MHz and 1414.5-1429.3 MHz). Each cube is saved as a fits file for each beam. These images are 1.1°×1.1°(661×661 pixels, with 6′′/pixel). The angular resolution of the imaging survey observations is ∼ 15′′×15′′/sin(δ). Please find more details in the Apertif DR1 Documentation.
