- observed elements of exterior orientation (auxiliary 
data) 
* EO, no observed exterior orientation elements 
* El, coordinates of the projection centres and 
camera rotations 
* E2, only the coordinates of the projection centres 
* E3, only camera rotations 
- precision of auxiliary data (standard deviations):

The standard deviations of the rotations are derived 
from the standard deviations of the camera position
