Ghost Trace Data

Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm )9+H[  
Type: Double Bounces +B4i,]lCx  
The '****' denotes a possible internal focus T^Hq 5Oy  
RMS is the RMS spot radius on axis at the primary wavelength. }U**)"  
RMS values of 0.00 indicate that an accurate RMS 9/O\769"'  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is \4uj!LgTb  
non-rotationally symmetric or uses non-standard surfaces.
