cds-question@unistra.frgalaxiesh-i-line-emissionWe present completed observations of the NGC 7448 galaxy group and background volume as part of the blind neutral hydrogen Arecibo Galaxy Environment Survey. Our observations cover a region spanning 5{deg}x4{deg}, over a redshift range of approximately -2000<cz<20000km/s. A total of 334 objects are detected, mostly in three overdensities at cz~7500, cz~9600 and cz~11400km/s. The galaxy density is extremely high (15deg^-2^) and many (~24%) show signs of extended HI emission, including some features as much as 800kpc in projected length. We describe the overall characteristics of this environment: kinematics, typical galaxy colours and mass-to-light ratios, and substructure. To aid in the cataloguing of this data set, we present a new fits viewer (FRELLED: fits Realtime Explorer of Low Latency in Every Dimension). This incorporates interactive source cataloguing tools which increase our source extraction speed by approximately a factor of 50.2014MNRAS.443.2634Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/443/2634CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/383/1519 : Abell 1367 HI sources from AGES (Cortese+, 2008)J/AJ/140/1093 : AGES NGC7332/7339 & NGC 1156 HI sources (Minchin+, 2010)J/MNRAS/415/1883 : AGES HI sources in NGC 7448 (Davies+, 2011)J/MNRAS/423/787 : AGES sources in Virgo cluster (Taylor+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/443/2634https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/443/2634http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/443/2634https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/443/2634https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/443/2634http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/443/2634GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/443/2634/table1 (AGES HI data for the NGC 7448 field)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/443/2634/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/443/2634/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/443/2634/table1?GETtext/xml+votable180.050000true342.41833315.0955560.005555555555555556Cone search capability for table J/MNRAS/443/2634/table2 (Optical data of AGES HI detections in the NGC 7448 field)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/443/2634/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/443/2634/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/443/2634/table2?GETtext/xml+votable180.050000true342.435416715.09052780.0055555555555555565/5002-5003 5006 5024-5025 6/19327 19413 19415 20003-20004 20006-20007 20018 20105 20108 20112-20114https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/443/2634?format=asciiRadiodefaultJ/MNRAS/443/2634/table1AGES HI data for the NGC 7448 fieldrecnoRecord number assigned by the VizieR team.
