Ghost Trace Data

Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm _T[m YY  
Type: Double Bounces >s+*D=k  
The '****' denotes a possible internal focus \t 04-  
RMS is the RMS spot radius on axis at the primary wavelength. 1VC:o]$  
RMS values of 0.00 indicate that an accurate RMS L/n?1'he  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is x"Q
