Distances of each component are plotted for the different methods in Sect. 7.1, at the respective ionisation parameters for 2000 (top) and 2014 (bottom). The data point shapes are shown in the legend, as are the colours for each component. The dashed line in each plot represents the location of the torus, at r_torus = 3.5 pc (García-Burillo et al. 2016), while the dotted line is at 1000 gravitational radii () from the SMBH, corresponding to a typical outer disk radius (Netzer 2013).
