Luminosity function code on toy data
------------------------------------
Figure 4.9.

An example of using Lynden-Bell's C- method to estimate a bivariate
distribution from a truncated sample. The lines in the left panel show the true
one-dimensional distributions of x and y (truncated Gaussian distributions).
The two-dimensional distribution is assumed to be separable; see eq. 4.85.
A realization of the distribution is shown in the right panel, with a
truncation given by the solid line. The points in the left panel are computed
from the truncated data set using the C- method, with error bars from 20
bootstrap resamples.
