Description:
We have visually examined 12 Palomar red plates for galaxies at low
Galactic latitude b, where the Supergalactic Plane (SGP) is crossed by
the Galactic Plane (GP), at Galactic longitude l~135deg. The catalogue
consists of 2575 galaxy candidates, of which 462 have major axis
diameter d>=0.8arcmin (uncorrected for extinction). Galaxy candidates
can be identified down to |b|~0deg. One of our galaxy candidates
(J24=Dwingeloo 1) has recently been discovered independently at 21cm
by Kraan-Korteweg et al. as a nearby galaxy. Comparisons with
structures seen in the IRAs and UGC catalogues are made. We compare
the success rate of identifying galaxies using the IRAS Point Source
Catalogue under different colour selection criteria. The criteria that
require both the 60- and 100-{mu}m fluxes to be of high quality have
the highest probability of selecting a galaxy (with d>=0.6arcmin), but
at the expense of selecting a smaller number of galaxies in total.

Note (1): The character denotes the plate label (as in table1) and
the number denotes the position in the list of galaxies spotted on
that plate. Hence an identification 'A25' refers to the 25th galaxy
spotted on POSS plate E1241. Galaxies that are identified more than
once in the plate overlaps will have composite labels, hence a label
A37L59 means that the galaxy is spotted on POSS plate E1241 and E973.
Note (2): Velocity listed in the Huchra's ZCAT that was available to us in 1991
Note (3): the flag takes the values
1: velocity is specified in ZCAT
-1: velocity is measured but not available to the public
