Description:
V- and I- band CCD photometry of the central 0.18 square degree of
Abell 168 was observed in November and December 1993 at the 1.05m Kiso
Schmidt telescope (f/3.1). The CCD chip has 1000x1018 pixels, the
pixel size is 0.752arcsec, giving a field of view of 12.0x12.7 arcmin.
The total observed region was covered by 7 individual CCD fields.
Note that some revisions were made by the author (TOMITA Akihiko)
compared to the original publication.

--------------------------------------------------------------------------------
Note (1): The position accuracy is 5arcsec to 15arcsec
depending on data quality.
Note (2): category is either of
E, S0, Se = early S [Sa-Sb], Sl = late S [Sc-Sd], I.
If we can see any bar structure, we add `B'.
Note (3): We use the following abbreviations;
LSB: low surface brightness;
DBL: double system (the companion has the comparable size);
COM: with a small companion (the number in parenthesis is the
ID-number of the companion, if it is catalogued as another
object in this list);
comp: companion;
dist: distortion;
r: red;
b: blue;
sb: semi-blue;
swb: somewhat blue.
Note that No. 39 is the only IRAS source and
No. 81 is the only radio source.

Nomenclature Notes:
[TNT96] is used to designate the galaxies (ID column of table3)
