Scientific paper

Luminosity-classification techniques have been used to study galaxies in 33 SRC Schmidt fields centered on the position of 'The Great Attractor'. A catalog and finding charts are given for 191 spiral galaxies, which are probably of DDO luminosity classes I, I-II, or II. Radial velocities of these objects should provide considerable insight into the three-dimensional structure of this region of space. The surface distribution of galaxies in the survey area is seen to be strongly affected by Galactic absorption. It is therefore not clear if any significance should be attached to the observation that there is no obvious concentration of galaxies at, or near, the position of The Great Attractor.
