The Extensible N-Dimensional Data Format (NDF) is a format for
storing bulk data in the form of N-dimensional arrays of numbers. It
is typically used for storing spectra, images and similar datasets
with higher dimensionality. The NDF format is based on the
Hierarchical Data System HDS (SUN/92) and is
extensible; not only does it provide a comprehensive set of standard
ancillary items to describe the data, it can also be extended
indefinitely to handle additional user-defined information of any
type.
This document describes the routines provided for accessing NDF data
objects. It also discusses all the important NDF concepts and includes
a selection of simple example applications.
