cds-question@unistra.frsurveyssupernovaeThis paper presents spectroscopy of supernovae (SNe) discovered in the first season of the Sloan Digital Sky Survey-II SN Survey. This program searches for and measures multi-band light curves of SNe in the redshift range z=0.05-0.4, complementing existing surveys at lower and higher redshifts. Our goal is to better characterize the SN population, with a particular focus on SNe Ia, improving their utility as cosmological distance indicators and as probes of dark energy. Our SN spectroscopy program features rapid-response observations using telescopes of a range of apertures, and provides confirmation of the SN and host-galaxy types as well as precise redshifts. We describe here the target identification and prioritization, data reduction, redshift measurement, and classification of 129 SNe Ia, 16 spectroscopically probable SNe Ia, 7 SNe Ib/c, and 11 SNe II from the first season. We also describe our efforts to measure and remove the substantial host-galaxy contamination existing in the majority of our SN spectra.2008AJ....135.1766Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/135/1766CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/sn : Asiago Supernova Catalogue (Barbon et al., 1999-)J/ApJ/659/122 : Improved distances to type Ia supernovae (Jha+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/135/1766https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/135/1766http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/135/1766https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/135/1766https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/135/1766http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/135/1766GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/135/1766/SNe (SDSS-II SN spectroscopic follow-up observations, redshift cross-correlation and type analysis)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/135/1766/SNe?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/135/1766/SNe?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/135/1766/SNe?GETtext/xml+votable180.050000true0.70566670.75133330.0055555555555555566/0 1 17406 17662 17663 17726 17727 17743 17749 17750 17752 17753 17754 17756 17761 17765 17770 17776 17777 17778 17807 17810 17811 17813 17816 17817 17818 17821 17827 17828 17831 17832 17833 17837 17856 17857 17981 17999 18001 18002 18003 18006 18007 18010 18014 18019 18020 18021 18022 18027 18028 18033 18061 18063 18065 18066 18072 18077 18082 18083 18084 18085 18086 18089 18091 18093 18094 18097 18112 18686 18687 18749 18751 18769 18780 18781 18789 18792 18794 18800 18802 18836 18841 18842 18843 18856 18859 18860 18866 18882 19025 19029 19031 19034 19035 19036 19038 19041 19043 19048 19049 19051 19052 19054 19090 19091 19092 19093 19094 19096 19097 19098 19107 19108 19115 19120 19137 19456 19457 19458 23102 23144 23182 23186 23187 23192 23196 23197 23203 23205 23206 23209 23211 23214 30034 30035 30037 30038 30039 30042 30044 30049 30055 30059 30064 30065 36861 36863https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/135/1766?format=asciiOpticaldefaultJ/AJ/135/1766/SNeSDSS-II SN spectroscopic follow-up observations, redshift cross-correlation and type analysisrecnoRecord number assigned by the VizieR team.
