For a single strip of 12 photographs, rigidly based 
on 5 ground control pts and flexibly on 12 height pts 
2l; photo pts 
12 camera stations 
12 principal pts 
leading to normals in 122 variables based on 136 
observation equations, 
For a single strip of 8 photographs, rigidly b ased on 
L, ground controls and flexibly on 6 height pts 
16 photo pts 
8 camera stations 
8 p rincipal pts 
leading to normals in 80 variables based on 86 
observation equations. 
For a single stereogram, with 6 Lawrence style double pts, 
6 flexible ground points and 6 flexible height points 
12 photo pts 
2 camera stations 
2 principal pts 
leading to normals in l6 variables based on 6l observation 
equations, 
For a single photo, with 7 photo pts, 5 of them rigid 
ground pts, 7 also floating height pts 
7 photo pts 
1 camera station 
1 principal pt 
leading to normals in 16 variables based on 20 observation 
equations, 
As for f), but not using the principal points, one 
has normals in 42 variables based on 60 observation 
equations.
