Planets inside the empirical habitable zone (EHZ). The left-most plot shows the frequency of planetary systems, of a given architecture class, which host at least one planet inside the EHZ. The central-left plot shows the fraction of planets inside a given architecture class which are in the EHZ. The central-right plot shows the fraction of all EHZ planets within a given architecture class. The rightmost plot shows the distribution of ƒice for EHZ planets across the architecture classes. The cartoon sketch of Earth emphasises that the only known life-harbouring planet resides in an ordered system. The length of error bars visualises the total number of systems or planets in respective bin as: 100/ bin eounts. The lengths of the error bars represents the number of planetary systems (left-most panel) and the number of planets (two middle panels) which are inside the bin. Large error bars in the leftmost panel, for example for anti-ordered architecture emerges from their low count (see Fig. 5). The Gaussian kernel is estimated using Scott’s rule (Scott 2015).
