The locations of the measured points are the same as in [1] but in order to 
separate P (principal point) and IT (nadir point) or c and z from each other 
at least two different z-values must be used. Three z-values are used in 
this case. Twentyseven points are thus measured in each projector (Pig 1 
and 2) and consequently 43 (54 - ll) redundant observations are obtained. 
All the setting values for the scales are given in Table 1.
