29 FUNCTIONAL DESCRIPTION
30 --------------------------------------------------------------------------------
31 This class models the stability derivative coefficient lookup tables or
32 equations. Note that the coefficients need not be calculated each delta-t.
34 Note that the values in a row which index into the table must be the same value
35 for each column of data, so the first column of numbers for each altitude are
36 seen to be equal, and there are the same number of values for each altitude.
38 See the header file FGFactorGroup.h for the values of the identifiers.
