Between August 2020 and June 2023, FASHI had covered more than 7600 square degrees, which is approximately 35% of the total sky observable by FAST. It has a median detection sensitivity of around 0.76mJy/beam and a spectral line velocity resolution of ~6.4km/s at a frequency of ~1.4GHz. As of now, a total of 41741 extragalactic HI sources have been detected in the frequency range 1305.5-1419.5MHz, corresponding to a redshift limit of z<0.09. By cross-matching FASHI sources with the Siena Galaxy Atlas (SGA) and the Sloan Digital Sky Survey (SDSS) catalogs, we found that 16972 (40.7%) sources have spectroscopic redshifts and 10975 (26.3%) sources have only photometric redshifts. Most of the remaining 13794 (33.0%) HI sources are located in the direction of the Galactic plane, making their optical counterparts difficult to identify due to high extinction or high contamination of Galactic stellar sources. Based on current survey results, the FASHI survey is an unprecedented blind extragalactic HI survey. It has higher spectral and spatial resolution and broader coverage than the Arecibo Legacy Fast ALFA Survey (ALFALFA). When completed, FASHI will provide the largest extragalactic HI catalog and an objective view of HI content and large-scale structure in the local universe. 2024SCPMA..6719511Z https://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/SCPMA/67.19511 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to II/294 : The SDSS Photometric Catalog, Release 7 J/AJ/142/170 : ALFALFA survey: the {alpha}.40 HI source catalog (Haynes+, 2011) J/ApJ/861/49 : ALFALFA extragalactic HI source catalog (Haynes+, 2018) https://www.legacysurvey.org/sga/sga2020 : SGA home page https://fast.bao.ac.cn : FAST Home Page https://cds.unistra.fr/vizier-org/licences_vizier.html https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/SCPMA/67.19511 https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/SCPMA/67.19511 http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/SCPMA/67.19511 https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/SCPMA/67.19511 https://vizier.iucaa.in/viz-bin/votable?-source=J/other/SCPMA/67.19511 http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/SCPMA/67.19511 GET text/xml+votable https://tapvizier.cds.unistra.fr/TAPVizieR/tap Cone search capability for table J/other/SCPMA/67.19511/table2 (FASHI extragalactic HI source catalog) https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/SCPMA/67.19511/table2? https://vizier.iucaa.in/viz-bin/conesearch/J/other/SCPMA/67.19511/table2? http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/SCPMA/67.19511/table2?
