Ghost Trace Data

Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm :f ybH)*  
Type: Double Bounces 0V"r$7(}  
The '****' denotes a possible internal focus IBcCbNs!  
RMS is the RMS spot radius on axis at the primary wavelength. f
`.8.1Rd  
RMS values of 0.00 indicate that an accurate RMS &kHp}\  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is S WVeUL#5  
non-rotationally symmetric or uses non-standard surfaces.
