If recordings of the exterior orientation parameters are 
available they are considered as well in the least squares 
adjustment. The corresponding observation equations read 
as:

AZ, k at line k and the corresponding values v' are their 
residuals. The observation equations (7), (8) and (9) to- 
gether form a rather large system of equations with 6n 
unknowns (n is the number of lines). Due to the fact, that 
the orientation parameters of a certain image line k are 
only tied with the parameters of the two preceding lines 
k-1 and k-2 the band width of the system is fairly small 
that is exactly 13.
