J/AJ/105/1251    Velocities in Pisces-Perseus supercluster.      (Wegner+, 1993)

A survey of the Pisces-Perseus supercluster. V. The declination strip +33.5 deg to +39.5 deg and the main supercluster ridge Wegner G., Haynes M.P., Giovanelli R. <Astron. J. 105, 1251 (1993)> =1993AJ....105.1251W (SIMBAD/NED Reference)
ADC_Keywords: Clusters, galaxy; Galaxies, optical; Combined data; Radial velocities; H I data; Redshifts Abstract: Measurements 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.

Note (1): For galaxies brighter than m=14.5, positions were obtained from Dressel & Condon (1976). For others, coordinates were obtained from the CGCG or, when higher accuracy than that of the CGCG is manifest, they were obtained from the Palomar Sky Survey (PSS) prints using a standard overlay program, with an estimated accuracy of 10". Note (2): Morphological type code index: 0 - Elliptical 1 - SO 3 - Sa 5 - Sb 7 - Sc 9 - Irregular 10 - Peculiar, with intermediate types allowed. A "B" indicates the presence of a bar. Note (3): For emission line-derived redshifts, the standard deviation of the mean for all the lines measured, or ±60 km/s, which is the estimated error for a single line in this sample. For absorption line-derived redshifts, errors are estimated from the JKFOUR program, to a minimum acceptable value of ±25 km/s. Note (4): A simple indicator of whether the spectral features used to derive the redshift were seen in emission (e) or absorption (a). For a handful of galaxies, velocities were derived from two absorption line spectra (x) and combining both absorption and emission lines (y).

Note (3): Telescope identification code: 0 - Arecibo 305 m with dual circular feed 1 - Green Bank 91 m 2 - Effelsberg 100 m B - Arecibo 305 m with linear feed major axis mapping. Note (4): Quality code: 0 - Object considered to be undetected at 21 cm. 21 cm line observations were performed, so we list the rms noise per channel of the observations. But no signal was detected; hence no flux is given. 1 - High quality detection 2 - Marginal to poor detection 3 - Flux and velocity ok, but profile unsuitable for use in T-F relation 4 - HI seen in absorption 5 - Confused with neighbor Note (5): The HI data reported here come from one of the following sources: 1 - This survey 2 - Northern Pisces-Perseus region (Haynes et al. 1988) 3 - Isolated galaxy survey (HG84) 4 - Survey of large angular diameter galaxies (Hewitt et al. 1983) 5 - Magri (1990) 6 - Sc galaxy survey (in preparation) Note (6): RV measured as the midpoint of the emission profile at a level of 50% of the mean signal intensity. When the object was considered to be undetected at 21 cm (Q=0), the velocity corresponds to the frequency of the central channel of the spectrometer Note (7): Adopted Local Group velocity, assuming a correction for the Sun's motion of 300 sin l cos b, where l and b are the galactic longitude and latitude. The adopted heliocentric velocity is the 21 cm velocity if the object is a high quality detection; if not, the optical velocity is adopted, when available.
