It contains columns for CCDID, nodeID and reference pixel location.
Their distance from the camera reference position in x,y and z are given in mm,
while the rotation of each CCD is in radians.
A second extension provides the description of the active field of view
in the form of region expressions.
The CCF contains the following tables:
- LINCORD :
- Table with data driving coordinate conversion routines; all geometry-related
data about the camera system are in the CCF; this CCF is not EPN-specific
