Top-down view on the Galactic plane, showing the uncertainty estimate (σ(ρ), left panels) and the absolute error (| m(ρ) − ρ|, right panels) for our reconstruction m(ρ) in units of cm-3. The input density ρ has fluctuations of medium strength and is sampled by 5000 pulsars with 5% distance uncertainty. The top row shows the scenario with unknown power spectrum and Galactic profile, the bottom row shows the scenario with known power spectrum and profile. We note that the left and right panels have different color bars.
