Graphical representation of the data model for our reconstruction. The logarithmic dust density log (ρ) is a Gaussian process with a smooth Gaussian process power spectrum . The true extinctions AG are directly dependent on the dust density ρ on each line of sight. The measured extinctions are assumed to be distributed around the true extinctions AG following a truncated Gaussian distribution as described in Sect. 3.2.
