Ghost Trace Data

Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm ~mt{j7  
Type: Double Bounces (>A#|N1U  
The '****' denotes a possible internal focus [ !#Dba#  
RMS is the RMS spot radius on axis at the primary wavelength. u28$V]
 
RMS values of 0.00 indicate that an accurate RMS PkyX,mr#1  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is ~Yg)
