Ghost Trace Data

Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm @Tsdgx8  
Type: Double Bounces 6<UI%X  
The '****' denotes a possible internal focus <%oT}K\;  
RMS is the RMS spot radius on axis at the primary wavelength. M5S<N_+Pe  
RMS values of 0.00 indicate that an accurate RMS fXkemB^)_  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is %'dsb7n  
non-rotationally symmetric or uses non-standard surfaces.
