cds-question@unistra.frsurveysgalaxiesinfrared-sourcesWe present a spectroscopic survey using the MMT Hectospec fiber spectrograph of 24um sources selected with the Spitzer Space Telescope in the Spitzer First Look Survey. We report 1296 new redshifts for 24um sources, including 599 with f_nu_(24um)>=1mJy. Combined with 291 additional redshifts for sources from the Sloan Digital Sky Survey (SDSS), our observing program was highly efficient and is ~90% complete for i<=21mag and f_nu_(24um)>=1mJy and 35% complete for i<=20.5mag and 0.3mJy<=f_nu_(24um)<1.0mJy. Our Hectospec survey includes 1078 and 168 objects spectroscopically classified as galaxies and QSOs, respectively. Combining the Hectospec and SDSS samples, we find 24 mselected galaxies to zgal<=0.98 and QSOs to zQSO<=3.6, with mean redshifts of <zgal>=0.27 and <zQSO>=1.1. As part of this publication, we include the redshift catalogs and the reduced spectra; these are also available through the NASA/IPAC Infrared Science Archive.2006AJ....132..231Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/132/231CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-tohttp://www.sdss.org/ : SDSS Home pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/132/231https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/132/231http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/132/231https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/132/231https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/132/231http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/132/231GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/132/231/table3 (SDSS-Matched 24 micron Catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/132/231/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/132/231/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/132/231/table3?GETtext/xml+votable180.050000true259.4604860.44670.005555555555555556Cone search capability for table J/AJ/132/231/table4 (*SDSS-Spectroscopic Catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/132/231/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/132/231/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/132/231/table4?GETtext/xml+votable180.050000true259.461560.283710.005555555555555556Cone search capability for table J/AJ/132/231/table5 (*Hectospec-Spectroscopic Catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/132/231/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/132/231/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/132/231/table5?GETtext/xml+votable180.050000true259.6036460.316260.005555555555555556Cone search capability for table J/AJ/132/231/table2 (Target Hectospec Fields)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/132/231/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/132/231/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/132/231/table2?GETtext/xml+votable180.050000true258.5812559.8580560.0055555555555555565/2547 2553 6/10183 10187 10194 10200 102026.772611666688002e-21 1.000830682546041e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/132/231?format=asciiInfrareddefaultJ/AJ/132/231/table3SDSS-Matched 24 micron CatalogrecnoRecord number assigned by the VizieR team.
