As my knowledge there is no weighted aperture.
If you want to see the secondary spectrum you can in the command window
key in follow:
Fie;lsa;go
It will show you the Field curv. and the Longitudinal Spherical Aber.
in cv_macro:flplot.seq
It will show you the focal shift vs. wavelength(secondary spectrum can see from it)
From above you can see the secondary spectrum.
How to corrected it ,it will by your knowledge and ability.
