Description

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:
