Between the mean values for y-parallaxes in 3*2 and 3*3 
a difference pf 1*7^* appeared* If one takes a level of 
probability of 95% this difference is significant* If 
however, the level of probability is fixed to 99%* there 
is no more significant difference* 
Strip tr.i angulation with the Analytical Plotter AP/C-3 
One strip with 5 models of the test area Heitlingen 
has been measured* Photo scale was is 7000 . In every 
model 12 natural points have been measured for relative 
orientation and point transfer. After relative orientation 
being complete, 12 signalized control points have been 
measured for strip adjustment, by polynomials. The table 
gives the time needed for this operations:

The results of the strip adjustment were unfortunately 
very disappointing. The residuls remaining in the 
control points were 3& cm in x and l7 cm in y* The only 
explanation that can be given for the moment is that there 
might be still some improprieties in program execution.
