The weight number of (335) including the measurement in an arbitrary 
point is finally found as 
322 y? X 3 
Un ar ER a 3 (B44) 
For a point p with the coordinates 
z= pb 
y=20 
we find from (344) 
3 n? + 3 p* — 2pn

Between the standard error of the elevation measurements and of 
the measurements of y-parallaxes we have the following relation from 
(254) and (256)

The weight number (345) becomes for the standard error of the y-
