Actual joint distribution of (p,β) (top left) of synthetic asteroids compared to the solution of the WISE-based inverse problem (top right). To make the solution plot more easily readable, we have plotted it from another perspective on the bottom right, with the z-axis depicting the weights w of each (p,β) bin. Here we have tested how accurately the solution is obtained if the peak of the distributions is low for p and high for β. On the bottom left is the solution with deconvolution.
