Abstract

The Hubble Space Telescope Calibration Database System collects and organizes data used in calibration of the many operating modes of the on-board scientific instruments. During the period form July 1995 to January 1997 the calibration data base system underwent a major redesign. The existing system had performed well since 1990 but some shortcomings were becoming apparent. The advent of two new science instruments, one of which has a very large number of operational modes, promised major complications. The new design operates with far fewer database tables yet provides extra functions. The tracking of replacement files has been improved, the maintenance of documentation has been simplified, and the process for installing data automated and streamlined. Additionally, various scripts have been written to perform checks on currently installed and historic data. This has resulted in a very efficient and reliable installation process which accommodates the new instruments and supports new data formats. It has also allowed us to detect and correct some discrepancies in the existing data that arose from occasional errors in the earlier manual procedures.
