APPENDIX 
Because of the fact that test data for square blocks (for which 
equation 4.41 was derived) were not readily available, the following 
results demonstrate the applicability of the newly developed formula to 
adjustment of strips. 
Table I shows the results obtained from a strip formed by using 
grid plates in the Wild Autograph A7. The strip is 17 models long at an 
equivalent scale of 1:40,000 and all ground coordinates are in meters. 
Three bands of three control points each were used in the beginning, middle 
and end of the strip. Each control point was fixed by all the three 
coordinates.
