Re: CDC geometry
Hi Beni,
I've just uploaded a plot to the wiki showing the z-component of the
vertex resolution for the nominal and modified stereo configurations as
you describe below. You can have a look here:

Note that the image is not linked from any page at this time.
Please let me know if you have any questions.
Regards,
-David
