Minimum-, Maximum Thickness (MinThk, MaxThk) and Total thickness variation (TTV) = (GBIR)

In an MX 203-8-37, e.g., a six inch wafer is measured at 21, a eight inch wafer at 37
sensor positions. The software computes the two thickness extrema, TTV (Total
Thickness Variation) is the difference between them.
