Ghost Trace Data

Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm A>S2BL#=  
Type: Double Bounces b&&'b)  
The '****' denotes a possible internal focus $RO=r90o  
RMS is the RMS spot radius on axis at the primary wavelength. )]Rr:i9n  
RMS values of 0.00 indicate that an accurate RMS .v!e=i}.  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is j(N9%/4u  
non-rotationally symmetric or uses non-standard surfaces.
