13.1 Overview

General calibration files or ``Cal G'' files contain either correction factors or instrumental parameters necessary to

steer the processing,
to remove or to correct for instrumental effects in the data, and
to carry out the flux calibration.

The contents of the Cal G files reflect the best or most recent instrument calibration parameters. The files can only be updated as part of an official upgrade of the OLP software. In this chapter detailed descriptions are given of the structure and contents of the Cal G files.
