M) Apertif DR1 - Polarization images and cubes

This service query provides for each observation A multi-frequency Stokes V image and Stokes Q and U cubes with a frequency resolution of 6.25 MHz. The Stokes V images are 3.4°×3.4°(3073×3073 pixels, with 4′′/pixel) while the Stokes Q and U cubes have a spatial extent of 2.7°×2.7°(2049×2049 pixels, with 4′′/pixel). These images are 1.1°×1.1°(661×661 pixels, with 6′′/pixel), which extend well beyond the 10% primary beam level. The angular resolution of the imaging survey observations is ∼ 15′′×15′′/sin(δ). Please find more details in the Apertif DR1 documentation
