This parameter is calculated using the formula (MaxDev - MinDev), where MaxDev is the maximum material on the contour, and MinDev is the minimum material on the contour.
For information on contour calculation, see "Modifying Flavor File Calculations".
LECONT and TECONT currently imply a least squares best fit. This fit uses all points up to the LE_CHANGE value.
