This paper presents the analysis of a deep near-infrared J,H,Ks-imagingsurvey (37.5 sq deg) aimed at tracing the galaxy distribution of the GreatAttractor (GA) in the Zone of Avoidance along the so-called Norma Wall. Theresulting galaxy catalog is complete to extinction-corrected magnitudes Ks^o =14.8 mag for extinctions less than A_K = 1.0 mag and star densities below logN(Ks<14.0) < 4.72. Of the 4360 cataloged galaxies, 99.2% lie in the herebyconstrained 89.5% of the survey area. Although the analyzed galaxy distributionreveals no new major galaxy clusters at the GA distance (albeit some moredistant ones), the overall number counts and luminosity density indicate aclear and surprisingly smooth overdensity at the GA distance that extends overthe whole surveyed region. A mass estimate of the Norma Wall overdensityderived from (a) galaxy number counts and (b) photometric redshift distributiongives a lower value compared to the original prediction by Lynden-Bell et al.1988 (~14%), but is consistent with more recent independent assessments.
