cds-question@unistra.frradio-galaxiesh-i-line-emissionradio-astronomyradial-velocityThe Arecibo Dual-Beam Survey is a "blind" 21 cm search for galaxies covering ~430deg^2^ of sky. We present the data from the detection survey as well as from the follow-up observations to confirm detections and improve positions and flux measurements. We find 265 galaxies, many of which are extremely low surface brightness. Some of these previously uncatalogued galaxies lie within the zone of avoidance, where they are obscured by the gas and dust in our Galaxy. Eighty-one of these sources are not previously catalogued optically, and there are 11 galaxies that have no associated optical counterpart or are only tentatively associated with faint wisps of nebulosity on the Digitized Sky Survey images. We discuss the properties of the survey, and in particular we make direct determinations of the completeness and reliability of the sample. The behavior of the completeness and its dependencies is essential for determining the H I mass function. We leave the discussion of the mass function for a later paper, but do note that we find many low surface brightness galaxies and seven sources with M_HI_<10^8^M_{sun}_.2000ApJS..130..177Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/130/177CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/130/177https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/130/177http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/130/177https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/130/177https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/130/177http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/130/177GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/130/177/table2 (Galaxy Detection Data)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/130/177/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/130/177/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/130/177/table2?GETtext/xml+votable180.050000true0.87708323.2010.005555555555555556Cone search capability for table J/ApJS/130/177/table3 (Optical Source Information)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/130/177/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/130/177/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/130/177/table3?GETtext/xml+votable180.050000true0.87726923.2000390.0055555555555555566/104 115 149 194 297 300 370 377 380 597 603 614 626 633 659 701 702 739 743 745 747 751 775 790 816 896 907 929 1044 1048 1067 2071 2121 2130 2181 4181 4182 4249 4279 4289 4291 4300 4301 4322 4361 4437 4439 4444 4446 4469 4473 4557 4559 4576 4685 4706 4725 4731 4801 4803 4804 4813 4824 4826 4867 4891 4908 4912 5024 5127 5139 5148 5152 5168 5170 5171 5172 5192 5280 6146 6151 6180 6184 6191 8295 8341 8357 8359 8416 8458 8460 8492 8545 8562 8599 8638 8640 8700 8716 8719 8901 8908 8939 8944 9004 9011 9216 9220 9248 10370 12450 12742 13108 13152 13330 13377 14338 18289 18290 18300 18384 18385 19537 19627 19894 19899 19900 19907 19942 19943 20051 20061 20218 20231 20237 20242 20248 20353 22421 22427 22434 22453 22468 23295 23404 23506 23528 23645 23657 23667 23672 23742 23783 23827 23915 23921 23933 23977 23984 24128 24170 24187 24252 24359 24395 26365 26460 26466 26535 26544 26548 26592 27479 27487 27504 27513 27515 27518 27570 27580 27601 27604 27735 27743 27763 27764 27770 27828 27830 27855 27857 27909 27913 27918 27921 27948 28015 28077 28101 28123 28126 28141 28147 28149 28167 28173 28184 28251 28267 28269 28272 28282 28283 28305 28309 28310 28355 28375 28416 28443 28444 28453 28461 28463 28464 28496 31630 31641 31919 32061 32163 32192 32226 32339 32427 32440 32451 32519 32522 32560 32585 32642https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/130/177?format=asciiOpticalRadiodefaultJ/ApJS/130/177/table2Galaxy Detection DatarecnoRecord number assigned by the VizieR team.
