Imaging field calibrations for linewidth on Geller MRS -3 NIST traceable line width and magnification standard measuring pitch are accurate to within 1% in X and less than 2.5% in Y for any magnification between 100 and 10000x. checked at 100, 1000, and 10000x magnification.  no evident pincushion or skew distortion is apparent on the screen or image captures.
  We will need to use linewidth and pitch standards generated on the RAITH 150 to calibrate higher magnifications and to evaluate imaging field distortion.  This is pending work within the Ebeam technology Groups Metrology section activities...
stay tuned,
