cds-question@unistra.frgalaxy-clustersgalaxiesvisible-astronomyradial-velocityh-i-line-emissionredshiftedMeasurements of 544 radial velocities, 229 optical and 315 in the 21cm HI line, are presented for galaxies, mostly in the declination strip +33.5 deg<Dec<+39.5deg in the region of the Pisces-Perseus supercluster. These are combined with other available data to investigate the linear structure identified as the main supercluster ridge. The main ridge of the supercluster extends at least 50h^-1Mpc before it disappears into the zone of avoidance east of Perseus. Confinement both on the plane of the sky and in the velocity dimension imply an axial ratio of greater than ten to one and an inclination with respect to the plane of the sky of less than about 12 degrees. The smoothed volume density contrast over the whole ridge averages more than a factor of 6 relative to the average density derived for the whole sample. The relative proximity, low inclination to the plane of the sky, and high contrast relative to the foreground and background, help to make the Pisces-Perseus filament one of the most prominent features in the extragalactic sky on large scales.1993AJ....105.1251Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/105/1251CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+AS/130/341 : Groups of Galaxies in PPS (Trasarti-Battistoni 1998)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/105/1251https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/105/1251http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/105/1251https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/105/1251https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/105/1251http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/105/1251GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/105/1251/table1 (Galaxies with new optical redshifts)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/105/1251/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/105/1251/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/105/1251/table1?GETtext/xml+votable180.050000true1.94625435.3615790.005555555555555556Cone search capability for table J/AJ/105/1251/table2 (Parameters of objects observed at 21 cm)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/105/1251/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/105/1251/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/105/1251/table2?GETtext/xml+votable180.050000true328.05800536.1002510.0055555555555555565/244 251 416 559 563 568 587-588 590 3380 3385 3388 6/822 907 928 932 940-941 948-949 951 953-954 957-959 971-972 974-975 980 982-983 986-987 989 995 997 999-1002 1011-1013 1019 1159 1184 1191 1211 1214-1215 1227 1248 1259 1554-1556 1560-1561 1563-1564 1566 1577 1579-1580 1586 1590 1593 1595 1602 1668-1670 1672-1673 1675 1680 1696 1705 1710 2128-2130 2132 2134 2140 2142-2143 2156-2157 2160 2164 2166-2167 2169 2172-2173 2175 2201 2206 2210 2214-2216 2218-2219 2222-2223 2227-2228 2230-2232 2243 2250-2251 2257-2261 2263-2266 2269-2270 2276 2280 2283 2285 2287 2289-2290 2297 2299-2300 2304 2306 2309-2311 2317-2318 2321-2323 2325-2326 2330-2333 2338-2342 2346-2347 2356-2357 2359 2368-2370 2378-2379 2384 2390 2397 2400 2432-2433 2437 2444 2560 2565 2568 2582 2585 2589-2590 2598-2599 2608 2610 2627-2628 2631 2636 2688 2693-2694 2704 3074 3105 6546 6825 12565 12567 13403 13405-13406 13426-13427 13430 13433 13439 13484 13503 13518-13519 13524 13526 13529 13535 13537 13545 13548-13550 13557-13558 13560-13561 13564 13570-13571 13580-13582 13588-13590 13592 13597 13601 13603 13606-13607 13611-13612 13616 13696-13698 13700 13703-13704 13706 13728 13845 13849 13877 13889 13894-13895 13898 13900 13906 19964-19965 20220 20284 20287 20298 20309 20311 20316 20321 20327 20336 20351 20357 20359 20372 20386 20392 20403 20410 20414 20419 20422 20429 20431-20432 20436 20438-20439 20441 20444 20446 20449 20454 20459-20461 20465https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/105/1251?format=asciiOpticalRadiodefaultJ/AJ/105/1251/table1Galaxies with new optical redshiftsrecnoRecord number assigned by the VizieR team.
