Summary:
A list of galaxies brighter than 18m with the coordinates in the
range RA=[10h42m,15h28m], Dec=[+28deg10min,+28deg10min] is
presented. The list contains data on apparent photographic
magnitude, angular, axial ratio and radial velocity for more than
300 objects. Emission and absorption line galaxies found show an
essentially different character in their spatial distribution.

Notes:
The following columns are not in the electronic version of table1:
- Linear diameter of the galaxy A=a*Vo/H, expressed in kpc, the
Hubble constant H being equal to 75 km/s/Mpc
- Absolute magnitude M=m-5log(Vo/H)-25-{DELTA}m, where
{DELTA}m=0.25+1.e-5*Vo accounts for average absorption value
at high galactic latitudes and the K-correction for a galaxy
of intermediate type.

41- 45 F5.2 arcmin AngDiam Angilar diameter in minutes of arc,
measured on the blue POSS print along
the major axis.
49- 52 F4.2 --- Axratio Axial ratio for the galaxy image on the
POSS blue print.
56 A1 --- Colour [±0] Indicator of colour of the
object:
+ for red galaxies
- for blue galaxies
#0 for neutral colour
57 A1 --- Structure [cdi] Object image structure flag:
c = compact
d = diffuse
i = irregular.
61- 65 I5 km/s RV [0/40000]? Radial velocity corrected for
the solar motion with respect to the
velocity centroid of the Local Group
using the standard formula
Vo = Vh + 300.sinl.cosb
66 A1 --- u_RV [:*] Radial velocity quality flag
: for unreliable velocity values
* marks those radial velocities taken
from elsewhere.
67- 69 I3 km/s e_RV [0/250]? Internal error of radial velocity
measurement
71 A1 --- Emission [ae] Emission line flag
e = presence of emission lines
a = absence of emission lines
74- 79 A6 --- Notes NGC or IC catalogue number of galaxy.

Note (1) Individual remarks:
# 23. Probably belongs to Seyfert-1 type.
# 37. Inner motion amplitude equals 192km/s
# 41. Spectral signs of Seyfert-2.
# 95. Declination is somewhat higher than the survey upper border.
# 110. Haro 31. The value Vo=7883±86 (DuPuy 1970) is not confirmed
by the Arecibo observations.
# 229. The radial velocity is measured at 21 cm in Arecibo. According
to Gregory (1975), Vo=+6654.
# 253. Vo=+10867 (Moody & Kirshner 1988).
# 256. Inner motion amplitude 210 km/s.
# 257. Inner motion amplitude 400 km/s.
# 321. Inner motion amplitude 133 km/s.
# 358. According to Strauss & Huchra (1988), Vo=+17342±56.
# 375. Instead of unreliable optical estimation Vo=+9300:±150
we give the velocity +9604±8km/s, measured at Arecibo.
