Geometrical accuracy and image quality 
  
If the plane of the original photograph is taken as reference, the 
total distorsion produced by the UT 1 is at maximum dx = dy = + 5 um 
  
in the image corners. This value refers to image transformation onto 
diapositive glass plate (Agfa-Gevaert Aviphot Dia C) from a grid 
plate (25 measured points). 
The AWAR resolution is better than 90 Lp/mm, for test targets with 
high contrast log. 2.0, also referred to the plane of the original, 
with transformation onto Agfa-Gevaert Aviphot Dia C PE film.
