cds-question@unistra.frradio-sourcesgalaxiesThe central challenge in 21cm cosmology is isolating the cosmological signal from bright foregrounds. Many separation techniques rely on the accurate knowledge of the sky and the instrumental response, including the antenna primary beam. For drift-scan telescopes, such as the Hydrogen Epoch of Reionization Array (HERA), that do not move, primary beam characterization is particularly challenging because standard beam-calibration routines do not apply (Cornwell et al.) and current techniques require accurate source catalogs at the telescope resolution. We present an extension of the method from Pober et al. where they use beam symmetries to create a network of overlapping source tracks that break the degeneracy between source flux density and beam response and allow their simultaneous estimation. We fit the beam response of our instrument using early HERA observations and find that our results agree well with electromagnetic simulations down to a -20dB level in power relative to peak gain for sources with high signal-to-noise ratio. In addition, we construct a source catalog with 90 sources down to a flux density of 1.4Jy at 151MHz.2020ApJ...897....5Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/897/5CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/35 : Radio Sources observed with Culgoora Circular Array (Slee 1995)VIII/100 : GaLactic and Extragalactic All-sky MWA survey (Hurley-Walker+, 2016)J/ApJ/771/105 : MWA Stokes I 189MHz sources (Bernardi+, 2013)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/897/5https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/897/5http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/897/5https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/897/5https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/897/5http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/897/5GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/897/5/table2 (List of sources used in this work and their derived flux density)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/897/5/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/897/5/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/897/5/table2?GETtext/xml+votable180.050000true22.59-26.120.0055555555555555566/20507 20519 20529 20535 20539 20543 20560 20597 20600 20612 20614 20625-20626 20644 20673-20675 20706 20744 20752 34264 34293 34303 34575 34616 34650 34653 34658 34665-34666 34669 34715 34755 35288 35295 35314 35325 35608 35639 35672 35696 35788 35792 36003 36010 36014 36100 36354 36378 38644 38648 38655 38703 38705 38708 38714 38763 38791 38793 38800 38805 38810 38819 38829 38833 38836 39614 39658 39676 39715 39722 39815 39841 39851 39854 40011-40012 40027 40029 40034-40035 40048 40051 40055 40119 40131 40137 40141 40195 402161.0005364593029448e-25 1.0005364593029448e-25https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/897/5?format=asciiRadiodefaultJ/ApJ/897/5/table2List of sources used in this work and their derived flux densityrecnoRecord number assigned by the VizieR team.
