We can see from the above plots that the difference of norms of $`\Sigma(k)\Sigma^{-1}(k)`$ and $`I(k)`$ is flaring-up after a certain rank. We can set a number for the flare-up by looking at the envelope of
the spread of the difference of norms. The spread is basically the standard deviation of this quantity.

The quantity $`\mu(k)`$ is the mean of the difference of norms and $`\sigma(k)`$ is the standard deviation.
The 10 largest likelihood samples are chosen to compute the spread. We can find the k_max for which the distance between these two curves along the y-axis is greater than a threshold, approximately O(1e-7).
In our analysis, we set this threshold to be $`2.4 \times 10^{-7}`$.
