The approximation written in Eq. (51) should have included an dependence inside the exponential:
The expression for in Eq. (54) should have been written using the limits
The negative sign in Eq. (56) should have been inside the exponent:
A factor of was missing from Eq. (57):
The use of was based on the approximation of Eq. (51) where the primary dependence was quadratic. The function was evaluated at the point of the curve that yielded under certain conditions. This was incorrectly interpreted as super-resolution behavior. Further research indicates the approximation expression improves performance at low to moderate frequencies but overestimates responses at high frequencies at moderate turbulence levels. In general is a moderate function of , , that falls below unity at high frequencies in such a way that diffraction limits are maintained. Enhanced responses () often appear for and .
