A_u By A_p B_p - gradients respectively for the left (L) and right (P) arm of the angle:

. Ax    Au

A =—■=---p, B = — --p,

Ax² + Ay²    Ax²+Ay²

dx_y dx_c, dx_p

,    ,    , - partial coordinates.

-    The correction equations in the matrix form:

V = A-x +w.

-    The solution of the system of standard equations:

(A^T ■p-A)-X+(A^T -p-w) = 0,

-x=(A^T -p-A)~' -(A^T -p-w).

-    Computation of adjusted coordinates:

X; =X? +dXy Yf =Y° +dy

-    Basic analysis of accuracy:

cov(x) = ml -(A^t ■p-A) ¹.

For the algorithm presented above there is created a codę that allows to adjust a network. The results can be displayed on a Computer monitor in a window. The application gives options of saving the results as text files in a chosen format and with freely indicated rangę. The adjustment itself can be executed with an appro-priate module of a complementary application (intemal) or with an external tool (for example an adjusting application built with VB). The way of executing the adjustment is chosen by indicating a proper option from the list at the start of com-putations. An exemplary window with an application thus realized is shown on figurę 8.
