The photocoordinates of points belonging to model 1 are given in 
Table 2.3.1 and the photocoordinates of points of model 2 are 
presented in Table 2.3.2. 
Table 2.3.3 shows the results of the application of the proposed 
technique, to the data of table 2.3.1, after introducing a 50mm 
gross error to the x, y coordinate of left photo. In this case no 
residuals for the x component are obtained. They are absorbed by the 
Z parameter of model. (for the first model, scale is arbitrarely 
introduced by bx). The difference of residuals gives better evidence 
of the presence of gross error in a certain y component, 
particularly because its sign is the oposit of most of the others.
