6dF Visualizations Supergalactic Cartesian Coordinates SGX Moving Slice 1000 km/s thick SGX from15000 to in steps of 500 km/s (No features labelled in this version) SGH Tony Fairall / University of Cape Town / Aug 06

‘Labyrinth’ software (written by C. Hultquist and S. Perumal)
Where two or more galaxies are separated by less than the percolation distance (i.e. in groups,clusters or large-scale structures), they are enclosed within a transparent surface. The percolation distance used here is 100 km/s in redshift space at cz=0, but increased with increasing cz to compensate for the drastic decrease in data density. The colours carry no meaning, except the blue serves to subdue the visual appearance of the distant structures (that look thicker since they were created with a larger percolation distance), in balance with the nearer structures.
