Calibration Access and Data Handbook

Description

It contains columns for CCDID, nodeID and reference pixel location (nominally the middle of 300,300 in RAWX,RAWY). 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:
