73 : // <synopsis>
74 : // The NewCalTable classes provide basic access to calibration tables. This
75 : // includes the creation of calibration tables, sorting and selection
76 : // capabilities, and basic data access. Specializations for baseline-based,
77 : // time-variable and solvable VisJones types, and sub-types, are provided
78 : // through inheritance.
79 : // </etymology>
