did not succed to introduce these tie conditions. So, the 
experiments with real image data are in complete with this 
respect. Nevertheless, I think it is quite interesting to regard 
the results we have achieved so far. 
|, EXPERIMENTAL RESULTS WITHOUT INTRODUCING 9 K 
sT* Üsgp^ Kar 
Two different series of experiments have been carried out. The 
first deals with real image data without use of readings of sm, 
Warm and Kam» @S already mentioned. The second series regards 
the numerical stability and correlation values of the system 
(chap. 5). For these investigations the constant terms in the 
equations do not play a part, so we may treat the complete 
system of equations in this respect. 
Now, at first let us compare the results we have achieved with 
all informations available (see /1/, tab. 3 and Abb. 6 for the 
residuals) to those with less informations, that means less 
photo series and / or less terrestrial points in testfield 2 
and 3, For the comparison we use the Hotelling-T^-statistios, 
see /1/, equations (23) - (25) and table 5. 
TESTFIELD 1: 
Without any risk only one series of photos may be used. This 
obviously is a consequence of the size and very high number of 
points in testfield 1. 
TESTFIELD 2: 
You may achieve safe and reliable results if more than one 
series of photos are used. But a certain unsteadiness can be 
observed. 
TESTFIELD 3: 
Due to the geometric uncompleteness of the mathematical model 
testfield 3 cannot deliver reliable results. For this type of 
testfield you cannot despense with the readings of the orien- 
tation angles Pam» n» and Kam» as has been possible in case 
of testfield 2 and especially of testfield 1.
