Mass architecture as a function of core-mass architecture. Panels compare the mass architecture with the core-mass architecture via the coefficient of similarity (left) and coefficient of variation (middle). In the left panel, the points corresponding to similar systems are very tightly clustered on the y = x line and are not visible due to over-plotting of points from other architectures. This signifies the core-mass architecture is very strongly correlated with the mass architecture for similar systems. The sum of mass in the envelope of each planet in a system is indicated in colour. The right panel plots the coefficient of similarity for masses and core masses for systems in the synthetically observed catalogues.
