Temporal error SWFE_temporal as a function of the sampling frequency f_s for various portions of the population corrected. For each eye, the temporal error is calculated as ${\text{SWFE}}_{\mathit{temporal}}={\sum }_{i=1}^{N_{\mathit{corrected}}}{\left({\sigma }_t\left(a_{i_{\mathit{res}}}\right)\right)}^2$. The temporal fitting error is shown in solid lines for a 0.5 loop gain and in dashed lines for a 0.1 loop gain. Symbols at 0 Hz indicate the dynamic SWFE obtained without any correction. (a) For a number of corrected Zernike modes N_corrected of 18 (i.e., up to the 5^th radial order). (b) For a number of corrected Zernike modes N_corrected of 42 (i.e., up to the 8^th radial order). Zernike modes piston, tip and tilt were excluded.
