The linearized intersection equations for points q in area la and all 
points r in area lb (Figure 2.03) take the form of equations 2.07 (a) and 
(b) merely by substitution of the proper subscripts ( q , r , respectively). 
The complete array of observation equations for triplet i , j , k is 
shown by equations 2.10 . The elements of the sub-matrices designated ijk
