Description:
CPL higher level data processing algorithms
The CPLDRS (DRS for Data Reduction System) implements higher level data processing algorithms (such as wavelength calibration, image recombination, dark-frame correction and so on). . 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").
