Angular Two-point Correlation Function
--------------------------------------
Figure 6.17

The two-point correlation function of SDSS spectroscopic galaxies in the range
0.08 < z < 0.12, with m < 17.7. This is the same sample for which the
luminosity function is computed in figure 4.10. Errors are estimated using ten
bootstrap samples. Dotted lines are added to guide the eye and correspond to a
power law proportional to :math:`\theta^{-0.8}`. Note that the red galaxies
(left panel) are clustered more strongly than the blue galaxies (right panel).
