J/AJ/105/1271   Pisces-Perseus supercluster. VI              (Giovanelli+, 1993)

A survey of the Pisces-Perseus supercluster. VI. The declination zone +15.5 deg to +21.5 deg Giovanelli R., Haynes M.P. <Astron. J. 105, 1271 (1993)> =1993AJ....105.1271G (SIMBAD/NED Reference)
ADC_Keywords: Clusters, galaxy; H I data Abstract: New results are presented of Arecibo observations in the 21 cm line of 765 galaxies with declinations between 15.5 deg and 21.5 deg, in the Pisces-Perseus supercluster zone. If considered independently on the neighboring parts of the sky, this region, to the South of the supercluster ridge, shows significantly less evidence of structure on large scales in excess of 30 Mpc, contrasting substantially with the characteristics of the declination zones immediately to the North.

Note (1): Morphological type code index: 0 - Elliptical 1 - SO 3 - Sa 5 - Sb 7 - Sc 9 - Irregular 10 - Peculiar 12 - Generic spiral (S...) 13 - Compact, unresolved morphology 14 - Compact spiral or irregular, with intermediate types allowed A "B" indicates the presence of a bar. Note (2): Telescope identification code: 0 - Arecibo 305 m with dual circular feed 1 - 300-foot telescope at Green Bank 7 - Arecibo 305 m with flat (linear polarization) feed Note (3): 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 (4): The HI data reported here come from one of the following sources: 1 - This survey 2 - Isolated galaxy survey (HG84) 3 - Survey of large angular diameter galaxies (Hewitt et al. 1983) 4 - Galaxy observed by the authors and I. Karachentsev as part of the thin galaxy survey based on the catalog of Karachentsev (1989); visual magnitude estimate on PSS. 5 - Not explained in the article Note (5): 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 detected 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
