CCDPACK: CCD Data Reduction Package

CCDPACK is a package of programs for reducing CCD-like data. They allow you to debias, remove dark current, flatfield, register, resample and normalize data from singleor multipleCCD instruments. CCDPACK is designed to help you to reduce your data easily. The basic reduction stages can be set up using an X based GUI that controls an automated reduction system. The GUI is designed to allow you to start working without any detailed knowledge of the package (or indeed of CCD reduction). Registration is performed using graphical, script based or automated techniques that help reduce the amount of work to a minimum. This document is intended for all users of CCDPACK. It provides instruction in how to use CCDPACK, describes CCD reduction in general and contains complete descriptions of the individual programs. iii SUN/139.18—
