Hessians (second derivatives of data misfit) obtained for the final models CUP20-OS6 (top) and CUP20-OCS5 (bottom), respectively. The parameters on the horizontal and vertical axes are ordered from left to right, and top to bottom, respectively. The outer index corresponds to layers and depths, with individual layers separated by the gridlines. The inner joint degree-order index is similar to Fig. 2, with the addition of (0, 0) term at the beginning of each layer block. Only the degree is annotated
