<div>It is not your English, it is very confusing. From the text it seems to imply that each of the input fields is to be "centered" and "scaled", resulting in a non-dimensional quantiy. But this is inconsistent with the units in the formula. I guess what they mean is that in each term, say</div>
<div> </div>
<div> (700mbTA - 4.5 10**(-5) ) / 7.3 10**(-5)</div>
<div> </div>
<div>the "4.5 10**(-5)" is the MCS sample mean and "7.3 10**(-5)" is the MCS sample stdv.</div>
<div> </div>
<div> This is my best guess.</div>
