First feedback on proofs

[jmorio44]

Dear Nelle,
thanks again for your editing work. Here are some first issues that I have found in the proofs:

• Tables 2 to 7 are generated with Python. As you see in the current version of the paper, the terms "mean", "opt" and "+d" are in italic font in these tables. They should have a normal font to be coherent with the notations of Table 1.
• In the PDF version of the proofs, the letter \mathbf{\Sigma} does not appear whereas it is ok in the HTML version. See for instance Eq. (3)
• We have found two minor typos: Section 5.3. line 5 "diagaonal" and Section 5.5 line 15 "stongly"
• There are still some warnings in the Table 7 of the article.
  Best regards,
