cds-question@unistra.frsurveysradio-galaxiesh-i-line-emissionradial-velocityThe Arecibo L-band Feed Array (ALFA) is being used to conduct a low-Galactic latitude survey, to map the distribution of galaxies and large-scale structures behind the Milky Way through detection of galaxies' neutral hydrogen (HI) 21cm emission. This Zone of Avoidance (ZOA) survey finds new HI galaxies which lie hidden behind the Milky Way, and also provides redshifts for partially obscured galaxies known at other wavelengths. Before the commencement of the full survey, two low-latitude precursor regions were observed, totaling 138deg^2^, with 72 HI galaxies detected. Detections through the inner Galaxy generally have no cataloged counterparts in any other waveband, due to the heavy extinction and stellar confusion. Detections through the outer Galaxy are more likely to have Two Micron All Sky Survey counterparts. We present the results of these precursor observations, including a catalog of the detected galaxies, with their HI parameters.2010AJ....139.2130Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/139/2130CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/125 : IRAS catalogue of Point Sources, Version 2.0 (IPAC 1986)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)VII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)J/A+A/505/29 : HI observations of 2MASS galaxies in ZoA (van Driel+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/139/2130https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/139/2130http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/139/2130https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/139/2130https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/139/2130http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/139/2130GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/139/2130/table1 (HI galaxy parameters from ALFA ZOA precursor observations)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/139/2130/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/139/2130/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/139/2130/table1?GETtext/xml+votable180.050000true281.141675.909170.0055555555555555565/6064 6/23965 23967 23974 23975 23978 23982 23983 23984 23987 23989 23992 23996 24002 24011 24012 24147 24153 24169 24170 24172 24174 24175 24215 24221 24222 24223 24229 24247 24249 24261 24263 24264 24265 24268 24323 24324 24325 24326 24331 30450 30509 30526 30593 30600 30604 30608 30609 30624https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/139/2130?format=asciiOpticalRadiodefaultJ/AJ/139/2130/table1HI galaxy parameters from ALFA ZOA precursor observationsrecnoRecord number assigned by the VizieR team.
