cds-question@unistra.frsurveysradio-sourcesphotometrygravitational-lensingredshiftedThe SuperCLuster Assisted Shear Survey (SuperCLASS) is a legacy programme using the e-MERLIN interferometric array. The aim is to observe the sky at L-band (1.4GHz) to a r.m.s. of 7uJy/beam over an area of 1 square degrees centred on the Abell 981 supercluster. The main scientific objectives of the project are: (i) to detect the effects of weak lensing in the radio in preparation for similar measurements that will be made by the Square Kilometre Array (SKA); (ii) an extinction free census of star formation and AGN activity at z up to 1. In this paper we give an overview of the project including the science goals and multi-wavelength coverage before presenting the first data release. We have analysed around 400 hours of e-MERLIN data which has allowed us to create a DR1 mosaic covering an area ~0.26 square degrees to the full depth. These observations have been supplemented with complementary radio observations from the Karl G. Jansky Very Large Array (VLA) and optical/near infra-red observations taken with the Subaru, Canada-France-Hawaii and Spitzer Telescopes. The main data product is a catalogue of 887 sources detected by the VLA, of which 395 are detected by e-MERLIN and 197 of these are resolved. We have investigated the size, flux and spectral index properties of these sources and find them to be compatible with previous studies. Preliminary photometric redshifts, and an assessment of galaxy shapes measured in the radio data, combined with a radio-optical cross-correlation technique to probe cosmic shear in a supercluster environment, are presented in companion papers.2020MNRAS.495.1706Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/495/1706CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/495/1706https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/495/1706http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/495/1706https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/495/1706https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/495/1706http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/495/1706GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/495/1706/subaru (Suprime-Cam data (table 4 of the paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/495/1706/subaru?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/495/1706/subaru?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/495/1706/subaru?GETtext/xml+votable180.050000true157.755058467.10193760.005555555555555556Cone search capability for table J/MNRAS/495/1706/vla (VLA data (table 4 of the paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/495/1706/vla?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/495/1706/vla?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/495/1706/vla?GETtext/xml+votable180.050000true156.89666484203568.11496533169190.005555555555555556Cone search capability for table J/MNRAS/495/1706/emerlin (e-MERLIN data (table 4 of the paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/495/1706/emerlin?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/495/1706/emerlin?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/495/1706/emerlin?GETtext/xml+votable180.050000true156.323051267.894875360.005555555555555556Cone search capability for table J/MNRAS/495/1706/list (List of fits images)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/495/1706/list?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/495/1706/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/495/1706/list?GETtext/xml+votable180.050000true156.3773368.175230.005555555555555556Associated datahttps://cdsarc.cds.unistra.fr/assocdata/?obs_collection=J/MNRAS/495/17066/7573 7575 7581 7616 7618 7624 194564.414320678087048e-20 5.517906024225661e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/495/1706?format=asciiRadiodefaultJ/MNRAS/495/1706/subaruSuprime-Cam data (table 4 of the paper)recnoRecord number assigned by the VizieR team.
