Description:
A new catalogue of 660 galaxies within a field of about 10 square
degrees in the Perseus cluster region is presented. The catalogue
contains accurate positions, isophotal magnitudes, angular radii,
position angles, radial velocities, morphological types, and detailed
informations on morphological peculiarities. If available, cross
identifications and radial velocities are also given. The catalogue is
estimated to be complete to a 25mag isophotal B magnitude of about 18.

Note on Mag25, SuBr:
Without corrections for Galactic foreground extinction and inclination.
Note on u_Mag25, u_SuBr:
Typical uncertainties of Mag25 are 0.1 to 0.2 mag. Larger uncertainties
due to difficulties in the removal of foreground stars are marked by a
colon
Note on REM:
1: a25, b25, PA are difficult to estimate for the individual components
of this merger system
2: Mag25, a25, b25, PA are related to the central knot;
the outer ring has a radius of 27 arcsec
Note on n_Mtype:
The following symbols are used:
IN: systems with signs of strong interaction in the form of
bridges (br) and/or tails (ta)
DIS: systems with signs of distortions, which can show one
or several of the following features coded by a number:
(1) peculiar spiral arms
(2) three-armed spirals
(3) M51 type
(4) unusual dust absorption
(5) elliptical galaxy with isophote twist
(6) non-concentric core
(7) loops/shells
(8) jet-like structures
(9) fuzzy structure in the outer regions
(10) radial spikes
CH(n): n systems (n>1) within a common halo
PL: polar ring galaxies or related objects
f*: estimation of morphology hampered by a nearby foreground star
The strength of the morphological peculiarity is indicated
(+ for strong, - for weak).
