How to apply a as-measured surface irregularity DAT file on the clear aperture of OAP?

Hi, all,

 

I have a as-measured surface irregularity file (converted from Zygo int into zemax dat file). I need to apply this on the clear aperture of off-axis parabola (OAP) surface. However, it seems that this DAT is applied on the vertex of OAP mirror, rather than the clear aperture of OAP. Is there a way to shift the DAT file so that it is applied on the clear aperture?  Thanks. 

[See the attached zar file for detail]

Hi, all,

I found the solution for this problem:  in the DAT file, change the “decenter Y” value, then the DAT file will move the he clear aperture of OAP.  Thanks!
