In both FASTSim 1 & 2 the abc_to_drag_coeffs functions do not constrain values to be physical (e.g. sometimes negative values can be returned). FASTSim 3 does not have this functionality at all, which is a different concern.
At least, we should ensure the calculated Cd and Crr are constrained to be positive, rather than coefficients for the least squares fit returned blindly.
