CDROM/AJ/V105/P1271 Pisces-Perseus Supercluster. VI (Giovanelli+ 1993) ================================================================================ A Survey of the Pisces-Perseus Supercluster. VI. The Declination Zone +15.5 deg to +21.5 deg Riccardo Giovanelli & Martha P. Haynes <1993, AJ, 105, 1271> =1993AJ....105.1271G ================================================================================ 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.

A "B" indicates the presence of a bar. MajAxis, MinAxis: Major and minor diameters from the UGC where available or else measured by eye from the PSS prints. Inc: Inclination derived from the axial ratio following Haynes & Giovanelli [1984, AJ, 89, 758]; hereafter referred to as HG84 m_c: Corrected magnitude, mc, after applying the corrections for galactic and internal extinction, redshift and systematic effects as discussed by HG84. Vsun: 21 cm line heliocentric velocity, Vsun, measured as the midpoint of the emission profile at a level of 50% of the mean signal intensity. V0: Adopted Local Group velocity, V(0) 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. W1: Observed 21 cm profile width, W1, measured at a level of 50% of the mean signal intensity. W2: Observed 21 cm profile width, W2, measured at a level of 20% of the peak signal intensity. Wc: 21 cm profile width corrected for viewing inclination and for redshift broadening. Fc: 21 cm line flux, Fc, after correction for random pointing errors, beam dilution, and HI internal absorption following HG84. Sigma: rms noise per channel measured in signal and interference-free portions of the spectrum. SNR: Signal-to-noise ratio of HI emission spectrum, measured as the ratio of peak signal flux to Sigma, after smoothing. Lum: Logarithm (base 10) of optical luminosity, h^2 L, in solar units, derived from m_c and scaled by the dimensionless Hubble parameter, h = H0/100 km/s/Mpc. M_H: Logarithm (base 10) of HI mass, H^2 M(H), in solar units, derived from Fc and V0. Tele: Telescope identification code for HI observations: 0 -- Arecibo 305 m with dual circular feed, 7 -- Arecibo 305 m with flat (linear polarization) feed. Qual: Quality code for HI detection: 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. Ref: Reference code for HI data. 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, AJ, 88, 272), 4 -- Galaxy observed by the authors and I. Karachentsev as part of the thin galaxy survey based on the catalog of Karachentsev (1989, AJ, 97, 1566); visual magnitude estimate on PSS. -------------------------------------------------------------------------------- ================================================================================ (End) Lee Brotzman [ADS] 28-Feb-1995
