The residual coordinate errors after an adjustment of one point com- 
bination can comparatively easily be computed. In Diagrams 13—14 
the residual coordinate errors of two plates from the R. C. 5-camera 
are demonstrated. The adjustment was performed in one combination 
of five points and the radial distortion was corrected. 
4.22 The film 
First the film was treated in the same manner as the plates. Immedi- 
ately it was found that the standard error of unit weight of the image 
coordinate measurements became much larger than for plates. In Table 
10 the standard errors from two films are demonstrated. 
The residuals are demonstrated in Diagrams 15 and 16.
