The left panel shows the case 
for 
with NN-kernel. The shaded area indicates the value 
(including the estimated error) of the exponent for the MVM with 
. For 
statistical errors increase because a smaller number of realizations was used as simulations become very costly. The right panel shows the case 
for 
with NN-kernel. The shaded areas display the value of the exponent for the MVM with both the NN- and square-kernel (K = 7) and the SSM with square-kernel (K = 7) for M = 100 and 
(i.e. 
).
