This figure shows the recurrent aberrations obtained after using MTS, MHS and NSA scaling methods. MTS is represented with thick red and grey, MHS with green and darkgreen lines and finally, NSA with red and black lines. The performance for MHS and NSA in terms of identifying recurrent aberrations is similar. NSA and MHS provide more significant values for the recurrent aberrations and no artificial aberrations appear. On the contrary, MTS introduces artificial aberrations.
