cds-question@unistra.frgalaxy-rotationredshiftedh-i-line-emissionWe have used the Westerbork array to carry out an unbiased wide-field survey for H I emission features, achieving an RMS sensitivity of about 18mJy/beam at a velocity resolution of 17km/s over 1800deg2 and between -1000<VHel<+6500 km/s. The primary data consists of auto-correlation spectra with an effective angular resolution of 49' FWHM. The survey region is centered approximately on the position of Messier 31 and is Nyquist-sampled over 60x30 deg in RAxDec. In this paper we present the results for our HI detections of external galaxies at positive Local Group Standard of Rest (LGSR) velocity. We detect 155 external galaxies in excess of 8 sigma in integrated HI flux density. Plausible optical associations are found within a 30' search radius for all but one of our HI detections in DSS images, although several are not previously catalogued or do not have published redshift determinations. Our detection without a DSS association is at low galactic latitude. Twenty-three of our objects are detected in HI for the first time. We classify almost half of our detections as "confused", since one or more companions is catalogued within a radius of 30' and a velocity interval of 400km/s. Nine of the detected galaxies fall so near the edges of the survey coverage (either spatially or in velocity) that their parameters can not be reliably determined. These nine objects are excluded from the enclosed table.2003A&A...406..829Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/406/829CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/406/829https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/406/829http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/406/829https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/406/829https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/406/829http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/406/829GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/406/829/wsrtgals (Properties of HI detected Galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/406/829/wsrtgals?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/406/829/wsrtgals?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/406/829/wsrtgals?GETtext/xml+votable180.050000true330.7041748.637780.0055555555555555566/626-627 689 697 701 724 731 742 747 752 759 765 896 903 922 929 932-933 938 941-942 948 952 955 1007 1013 1768 2063 2071 2096 2121-2122 2130 2142 2145 2169 2181 2218 2242 2253-2254 2261 2272 2286 2312 2320 2324 2329 2333 2339 2347 2354 2370 2372 2374 2377 2382-2383 2387 2391 2394 2406 2409 2411 2417 2427 2433 2453 2485 2504 2518 2564 2622 2654 2661 2687 2718 2726 2728 2792 2836 2838 2866 3072 3075 3120 13336 13375 13391 13461 13510 13516 13522 13535 13558 13632 13668 13672 13693 13782 13900 13903 13907 13913 13943-13945 13948 14033 14041 19961 20090 20177 20188 20207 20223 20237 20254 20271 20277 20298 20352-20353 20361 20371 20388 20390 20396 20400 20403 20417 20424 20432 20438 20448 20476https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/406/829?format=asciiOpticalRadiodefaultJ/A+A/406/829/wsrtgalsProperties of HI detected GalaxiesrecnoRecord number assigned by the VizieR team.
