Fig. 3
Dust density (attenuation per parsec) drawn from the prior with different hyperparameters of the covariance function (Eq. (9)). We define a 1D grid of 1000 equally-spaced points from r = 0 to r = 5000 pc and each red and black line shows one draw from a 1000-dimensional Gaussian for a fixed λ and θ.
