Ghost Trace Data

Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm V*?c
MJ_G  
Type: Double Bounces VF?H0}YSHb  
The '****' denotes a possible internal focus b| L;*<KU  
RMS is the RMS spot radius on axis at the primary wavelength. $)M3fZ$#  
RMS values of 0.00 indicate that an accurate RMS D+7xMT8pqH  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is 0*{(R#  
non-rotationally symmetric or uses non-standard surfaces.
