Description:
A deep optical galaxy search in the southern Milky Way - aimed at
reducing the width of the Zone of Avoidance - revealed 3279 galaxy
candidates on the IIIaJ film copies of the ESO/SRC survey above the
diameter limit of D greater than approximately 0.2 arcmin. Only 112
(3.4%) were previously catalogued. The surveyed region (266<l<296
and -10<b<+8) lies in the extension of the Hydra and Antlia
clusters.
Optical properties of the unveiled galaxies such as positions,
diameters, magnitudes, morphological types are given in Table 1.
Cross-identifications with the IRAS PSC (Cat. II/125) are given in
Table 2.

Note (2): The IRAS flags are coded as:
1 = lower limit
2 = uncertain flux
3 = good flux quality
--------------------------------------------------------------------------------
Global Notes:
Note (G1): the quality of the IRAS cross-correlation is explained
in section 3.3 of the paper. They are schematically:
I = certain IRAS connection
P = possible match in the IRAS PSC
Q = questionable (unlikely) match in the IRAS PSC
The code may be followed by a number indicating the equally
possible galaxy counterparts for a given IRAS source.
N = cross-identification is not accepted, further detailed as
NG = another galaxy is concerned
NS = is a star
Note (G2): Morphological classification:
The morphological types are coded similarly to the precepts of the RC2
(de Vaucouleurs et al., 1976, Cat. VII/112). Due to the varying
foreground extinction a homogenous and detailed type classification
could not always be accomplished and some codes were added.
In the first column, a question mark denotes the uncertainty about the
galaxian nature of the object.
In the second column, the code F for the Hubble type E-S0 (T=-3 in the
RC2 classification) was added to the normal designations of E, L, S and I.
In third subcolumn, the subtypes E, M and L are introduced next to the
general subtypes 0 to 9. They stand for early spiral (S0/a-Sab),
middle spiral (Sb-Sd) and late spiral or irregular (Sdm-Im). The
cruder subtypes are a direct indication of the fewer details visible
on the obscured galaxy image.
The questionmark at the end marks uncertainty of the main type, the
colon uncertainty in the subtype.
The third column marks the orientation of the galaxy: E, N, F, V
stands for edge-on, nearly edge-on, face-on and nearly face-on. The
fourth subcolumn indicates the superposition of a single star (1) or
multiple stars (S) on the galaxy.
