These figures use real data, from the selected areas SA57, and SA68, the photometry due to R. Kron and D.C. Koo, and the redshifts are spectroscopic, obtained at the Kitt Peak National Observatory, on the 4m Mayall telescope. The data set consists of 9854 galaxies with multicolor photomoetry in U,J,F and N, out of which 254 galaxies have high quality redshifts as well. This is a visualization of the distribution of the 254 galaxies with both multicolors and redshift, in the space of the broadband magnitudes. The axes are the U,J,F magnitudes. Click on these pictures to see the strong correlation between the different colors and redshifts.
All data points are close to a slightly curved surface.
