If the monochromatic error function of optical systems is computed analytically by means of aberration coefficients, certain intermediate results of this computation can be used for the investigation of the aberration balance. For the analysis of local minima resulting from optimization, a new automatic technique has been developed that groups together monochromatic aberrations having a large mutual compensation of their effect on the error function. Criteria are proposed to evaluate the
