Matrix-based compression can be for predefined relative energy $\gamma$ (which affects RE) or set to achieve desired compression, so we performed both. For experiment 1 with ${\gamma }_1$, the $k_2$ and $\left(k_1,k_2,k_3\right)$ values that gave the same compression results were 25 and (92, 69, 69), respectively; for the second experiment these were 11 and (70, 53, 53), respectively. Truncations for the matrix case were 65 and 25 for the ${\gamma }_1$ experiment and 47 and 11 for the second.
