dc.descriptionIn an analysis of the IRAS 1.2 Jy redshift catalogue, with emphasis on the separate examination of northern and southern parts (in galactic coordinates), we found that the clustering of galaxies differs significantly between north and south, showing fluctuations in the clustering properties at least on scales of 100 Mpc/h (Kerscher et al. 1997, astro-ph/9704028). We give a brief description of our morphological method which is based on Minkowski functionals and show the results obtained from the IRAS 1.2 Jy galaxy catalogue. We discuss several error estimates and select different subsamples from the 1.2 Jy catalogue according to flux and colour and validate the results for the whole sample. Furthermore we look closer at the spatial origin of the fluctuation and we compare with optically selected galaxies from the CfA1 survey.
