Ghost Trace Data

Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm ,/f\  
Type: Double Bounces 1Lb)S@Q`*R  
The '****' denotes a possible internal focus g}_2T\$k  
RMS is the RMS spot radius on axis at the primary wavelength. _Ewh:IM-  
RMS values of 0.00 indicate that an accurate RMS j7}mh  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is ;4 ;gaf  
non-rotationally symmetric or uses non-standard surfaces.
