in which (Sn)cor and (Sjjj)cor are the "central" contributions, i.e. the contributions of the corrector if the stop were in its plane. Eq. (4.4) is the same as for the aspheric plate since the lens corrector is afocal:
For a parabolic primary, Z = 0 giving
Since [4.22] for a "thin", afocal corrector S/// = H2(Ki + K2) = 0, the equations give for E S// = E S/// = 0
