# CCDRED Data Structures and Definitions
# The CCD structure: This structure is used to communicate processing
# parameters between the package procedures. It contains pointers to
# data, calibration image IMIO pointers, scaling parameters, and the
# correction flags. The corrections flags indicate which processing
# operations are to be performed. The subsection parameters do not
# include a step size. A step size is assumed. If arbitrary subsampling
# is desired this would be the next generalization.
