In chronological order:

Check out the clear segregation there is in A2192 in this (3D image) ra-dec-z plot in this video:

Only members of the main cluster are plotted. sub-structure withing the cluster is shown in different colours (red, gray, yellow and turquoise). Blue transparent cubes represent HI-detections and orange transparent cubes represent galaxies with OII in emission!

UPDATE: More info added to the plots!

(7 Feb 2012) In the following animations, I've combined the HI, OII, position, z, and morphology information!

A2192: The colours highlight substructures identified in the cluster, while the symbols correlate with morphology: early-type (E/SO) galaxies are plotted in big solid circles, and late-types (S,Irr,and interacting) in solid cubes with spikes. The smaller symbols correspond to galaxies with no morphological classification. Morphologies were defined (visually) from WHT B- and R-band images.

Transparent blue cubes trace the HI content in the galaxies (from deep Westerbork Synthesis Radio Telescope observations). Transparent orange cubes instead highlight the location of galaxies with emission (EW[OII]>4A).

ONLY GALAXIES WITH WHT OBSERVATIONS ARE PLOTTED, TO GET AN IDEA OF THE RELATIVE FRACTION OF OII-EMITTING AND HI-EMITTING GALAXIES
