Dear Siv,
Would it also be possible to get a copy of that table?

Yes, the zoom is real, restricting the deflection angle of the galvos  
to a smaller field.  As I recall, galvo deflection voltage on is set  
in 8-bit increments on the 1000/1024 scanner. Zooms that are not in  
multiples of 2 will have interpolation errors causing some variation  
in positioning.  I may be wrong on the details, but couldn't find the  
old discussion thread in the archives.  Pixel size at zoom =1 for any  
lens will be affected by calibration of  scan area by the service  
engineer and variation in total mag to the detector, which is  
slightly different for each system, at least for the MRC systems.

Regards,
Glen

I've looked for that line myself.
