Interactive 3D visualisation software: Mollweide projection. Mollweide projection of the LSS for galaxies (black points) in the redshift range 0.030 <z< 0.035 as shown in the blue bars in the lower part of the figure (default values). Red disks represent isolated galaxies within the same redshift range. Isolated pairs and isolated triplets can be shown by selecting the samples in the sample box (panel in the left part of the figure). The transparency of the represented samples can be modified by sweeping the blue bar under the samples box. To guide the eye, a wedge diagram, for LSS galaxies within −2 and 2 deg in declination, is shown in the right lower part of the figure. Colour code according to the redshift from z = 0 (blue) to z = 0.10 (red). The red ring in the polar representation corresponds to the selected redshift range in the central Mollweide projection. One can return to the default values with the reset button.
