Abstract:
The new instruments to be installed during the 1997 servicing mission
for the Hubble Space Telescope present challenges of managing complex
associations among a variety of data. The data structures and the
design of the I/O software interface to support these instruments are
presented. The significance of this software architecture to the
design of calibration algorithms is that it allows the implementation of
algorithms, based on accessing data in a logical form, abstracting from
the details of disk formats. The architecture also illustrates the
principle of encapsulation, concealing the details of implementation
from the developers of algorithms. The consequences of this approach
are discussed.

Software and Systems (ADASS V) held in Tucson, Arizona, on October 22-25,
