Abstract:
This paper presents the first results of a 21cm survey of newly
discovered optically selected galaxies behind the Milky Way. We
present 40 radial velocities of the new galaxies and 15 velocities of
UGC and MCG galaxies in a region where the well known
Pisces-Perseus-Supercluster (PPScl) is supposed to be veiled by
galactic extinction (80deg≲l≲110deg). Twenty-four galaxies have
radial velocities between 4000 and 6000 km/s that fit to the values
usually accepted for the PPScl. We could pursue this supercluster at
least to b=-5 deg around l=90 deg.

Note (1):
a: These galaxies have been observed in several sessions for consistency
b: Two separate profiles in one spectrum because of two galaxies within
the beam at different velocities
c: Unusual large profiles (either a very HI-rich galaxy or two galaxies
at similar velocities)
d: Several galaxies within 9 ' (beam width) are visible on the
Palomar-red-prints
Note (2):
*: 107.12+03.41 has also been measured in the 21cm line by Martin et al.
(1990). They give a radial velocity of 3504±5 km/s in excellent
agreement with our value.
