Description:
Fundamental CPL data types and functions
The CPLCORE library provides the fundamental CPL data types (such as cpl image, cpl table, cpl vector, cpl matrix etc.), the operations defined on these data types, and elementary utility functions. There should not be any physical units associated with any of the data types or functions of that library. . The Common Pipeline Library (CPL) comprises a set of ISO-C libraries that provide a comprehensive, efficient and robust software toolkit. It forms a basis for the creation of automated astronomical data-reduction tasks (known as "pipelines").
