accurately would require even higher levels. Since the 8D-Level4 run took 12.5 h,
we decided not to go to higher dimensions, until we were absolutely forced to. In
fact, it is probably wiser to use voxel-based inverse methods when the number of
parameters needed to accurately model the geometry of the problem exceeds, say, 5
or 6.
We also studied the convergence of 4D-Level 6 to 4D-Level 8, and find excellent
results. Hence, the remainder of our study at this point will concentrate on 4DLevel 8 situation. As a starter, we show in Figs. 9.13, 9.14, 9.15, 9.16, 9.17, 9.18,
9.19, 9.20, 9.21, 9.22, and 9.23 a comparison of interpolated results at 81 arbitrarily
selected points with the TASMANIAN grid at level 8 with 1857 Chebyshev points.
