For the case of dependent pictures at the relative 
orientation we have the wellknown formula

The y-parallaxes are eliminated at the relative orien- 
tation with the aid of the orientation elements dby, and 
duo + (See equation (3)). The corrections to these two ele- 
ments of orientation as functions of the centering errors 
are found as demonstrated in equations (5) and (6).
