 ## Output File ###
 The Output file is composed by two structures: `Coeffs` and `State`. 
-`Coeffs` contains all the aerodynamic coefficients interpolated over the 4 states (AoA, Mach, Altitude, Sidesplip angles) and the struct `State` contains the set of states (Aoa, Mach, Altitude, Sideslip Angle) the coefficients have been calculated on and the position of the center of gravity.
