VizieR Online Data Catalog: SuperCLASS. I. (Harrison+, 2020)
Abstract
Three catalogues are provided containing L-band optical and BVr'i'z' brightness and morphological data for sources in the SuperCLASS field, consisting of ~1 square degree in the Northern sky. Catalogues superclassvladr1 and superclassemerlindr1 were created using data from the VLA and e-MERLIN radio telescopes respectively on the 0.26 square degree DR1 region. VLA data is from 24 hours of observing over 112 pointings in A configuration in the 1-2GHz (L-band). The correlator was configured to deliver 250kHz spectral channels (a total of 4000) in full polarization with 1s time sampling. e-MERLIN data is from 49 pointings over the Northern part of the same field, from ~400-hours of data taken in the frequency range 1.204-1.717GHz, with 512 spectral channels of width 125kHz and 1s time integrations. Both sets of radio data were imaged using forms of the CLEAN algorithm. The VLA image Gaussian restoring beam had major axis 1.9arcsec, minor axis 1.5arcsec and position angle 80deg east of north. The e-MERLIN Gaussian restoring beam had major axis of 0.417arcsec, minor axis 0.232 arcsec and position angle 147.93deg east of north. Sources in VLA images were detected and had their fluxes measured using the PyBDSF software and all output columns from this are provided, along with morphological classifications and measurements from the IM3SHAPE and SuperCALS pipelines described in the accompanying papers. Sources in e-MERLIN images were detected and had their fluxes measured using the PyBDSF software, with catalogues being the union of detections made with three smoothing scales applied to the image (0.4, 0.6, 2.0-arcsec). The catalogue superclasssubarufull is for the full 1.755 square degree SuperCLASS region. This contains AB magnitudes measured from the Subaru Suprime-Cam observations of the SuperCLASS field in BVr'i'z' bands. Sources were detected using the SExtractor software, before having their redshifts inferred using the EAZY software and their morphology measured with the IM3SHAPE software.
