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
