Note : this is the description file of the original catalog. This HTML page corresponds well to the original description, but some minor changes in the format may have been introduced in the FITS output files in order to allow for arithmetic operations on quantities such as coordinates and times. h:m:s and d:m:s units are normally converted into degrees, and YYYY-MM-DD into julian days.
Similarly, some slight changes may have been introduced in the units; the value given in the HTML files supersedes the value indicated in the ReadMe file for this catalogue.

    Abstract:
        In this second paper of the catalogue series of galaxies behind the
        southern Milky Way, we report on the deep optical galaxy search in the
        Crux region (289°<~l<~318° and -10°<~b<~10°) and the
        Great Attractor region (316°<~l<~338° and
        -10°<~b<~10°). The galaxy catalogues are presented, a brief
        description of the galaxy search given, as well as a discussion on the
        distribution and characteristics of the uncovered galaxies. A total of
        8183 galaxies with major diameters D>~0.2 arcmin were identified in
        this ~850 square degree area: 3759 galaxies in the Crux region and
        4423 galaxies in the Great Attractor region. Of the 8183 galaxies, 229
        (2.8%) were catalogued before in the optical (3 in radio) and 251
        galaxies have a reliable (159), or likely (92) cross-identification in
        the IRAS Point Source Catalogue (3.1%). A number of prominent
        overdensities and filaments of galaxies are identified. They are not
        correlated with the Galactic foreground extinction and hence
        indicative of extragalactic large-scale structures. Redshifts obtained
        at the South African Astronomical Observatory (SAAO) for 518 of the
        newly catalogued galaxies in the Crux and Great Attractor regions
        (Fairall et al., 1998, Cat. J/A+AS/127/463; Woudt et al., 1999, Cat.
        J/A+A/352/39) confirm distinct voids and clusters in the area here
        surveyed. With this optical galaxy search, we have reduced the width
        of the optical `Zone of Avoidance' for galaxies with
        extinction-corrected diameters larger than 1.3' from extinction levels
        A_B>~1.0mag to A_B>~3.0mag: the remaining optical Zone of Avoidance is
        now limited by |b|<~3° (see Fig. 16).

    Note (2): Morphological classification (from Kraan-Korteweg, 2000,
               Cat. J/A+AS/141/123)
        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 (byte 115), a question mark denotes the
          uncertainty about the galaxian nature of the object.
        - In the second column (bytes 117-121), 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 byte 131, 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 (byte 123) 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 (byte 125) indicates the superposition of a
          single star (1) or multiple stars (S) on the galaxy.

    Note (1): Y: galaxy listed by Yamada et al., 1993, Cat. J/ApJS/89/57
        *: the IRAS PSC source satisfies all the Yamada et al. selection
            criteria, yet was not listed in Yamada's catalogue.
    Note (2): The IRAS flags are coded as:
          1 = lower limit
          2 = uncertain flux
          3 = good flux quality

    Global notes:

    Note (G1): Quality of the IRAS cross-correlation is explained in 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
