Maximum likelihood best-fit parameters for a set of 100 simulations. The dotted lines show the true, original values used: κ = 1.5 star pc^-2, β = 1.8, A₀ = 0.3 mag, and σ = 0.5 pc. Note how the points, representing the individual best-fits, cluster around the true values. The ellipses, showing the expected 3-σ errors as deduced from the Fischer information matrix, are in excellent agreement with the observed distribution of points.
