cds-question@unistra.frsurveysh-i-line-emissionradial-velocityDetails are presented of the H I Jodrell All Sky Survey (HIJASS). HIJASS is a blind neutral hydrogen (H I) survey of the northern sky ({delta}>22{deg}), being conducted using the multibeam receiver on the Lovell Telescope (full width at half-maximum beamwidth 12-arcmin) at Jodrell Bank. HIJASS covers the velocity range -3500 to 10000 km/s, with a velocity resolution of 18.1km/s and spatial positional accuracy of ~2.5arcmin. Thus far about 1115 deg^2^ of sky have been surveyed. The average rms noise during the early part of the survey was around 16mJy/beam Following the first phase of the Lovell Telescope upgrade (in 2001), the rms noise is now around 13mJy/beam. We describe the methods of detecting galaxies within the HIJASS data and of measuring their H I parameters. The properties of the resulting H I-selected sample of galaxies are described. Of the 222 sources so far confirmed, 170 (77 per cent) are clearly associated with a previously catalogued galaxy. A further 23 sources (10 per cent) lie close (within 6 arcmin) to a previously catalogued galaxy for which no previous redshift exists. A further 29 sources (13 per cent) do not appear to be associated with any previously catalogued galaxy.2003MNRAS.342..738Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/342/738CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/342/738https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/342/738http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/342/738https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/342/738https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/342/738http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/342/738GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/342/738/table2 (The sample of confirmed HIJASS sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/342/738/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/342/738/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/342/738/table2?GETtext/xml+votable180.050000true0.62958377.2952780.0055555555555555566/2155 2169 2242 3175 3186 3193 3281 3313 3323 3325 3331 3466 3480 3483 3488-3490 3492-3494 3496 3499-3501 3503 3505-3507 3510-3511 3516-3517 3519 3541 3545 3549-3550 3555 3559 3567-3568 3573 3579 3669 3838 3860 3862 3865 3868 3871 3889 3894 3900 3904 3907 3909-3910 3912 3914 3922 3938 6129 6137-6138 7485 7498 7501 7504 7523 7534 7536 7540-7542 7547 7572-7573 7576 7583-7584 7590 7600 7602 7604 7606-7607 7624 7627 7636 7649 7653 7655 7658-7659 7662 7679 7799 7869 7871 7882 7893-7895 7898 7901-7903 7915 7928 7946 7956-7957 7966 7970 7980 7983 7986 7988 7991 7997 8001 8004 8011 8015 8032 8034 8042 8064 8067 8072 8074 8082 8084 8088 8101 11724 11726 11729 11731 11734 11736 11738 11764 11769 11772 11965 11975 11995 12001 12005 12017 12020 12022 12024 12026-12028 12030-12031 12116 12122 12170 15806-15807 15823 15845 15847 15866 16098 16120 16149 16194 16197-16198 16205 16260-16261 28087 28091 28131 28435 28438 28444 28483 28486 28493-28494 28498 28505 28513-28516 28519 28521https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/342/738?format=asciiOpticalRadiodefaultJ/MNRAS/342/738/table2The sample of confirmed HIJASS sourcesSpeak21cm peak flux densitymJyintrecnoRecord number assigned by the VizieR team.
