Release Notes - V1.3-2

Two new converters, HDS2IDL and IDL2HDS, are provided for IDL users. They handle complete structures, unlike READ_NDF and WRITE_NDF which only handle the main arrays of NDFs.

NDF2FITS and FITS2NDF have been enhanced by the addition of FITS-AIPS and FITS-PC encodings. Also, appropriate messages are output if there are no valid input files.

FITS2NDF has also been enhanced to allow more flexibility over the handling of multi-extension FITS files. Syntax such as filename.fit[1] or "filename.fit[extname=im2]" can be used to specify a single FITS extension to be converted, and additional parameters EXTABLE and CONTAINER allow FITS extensions to be combined to produce a single NDF or a series of components of a top-level HDS container file.

The scripts associated with the NDF on-the-fly conversion system have been modified to allow a single extension from a multi-extension FITS file to be specified. This feature requires applications to have been built with NDF V1.5-6 or later.

Different numbers of axes in the BaseFrames of the NDF and FitsChan FrameSets are now allowed when creating the NDF's WCS component.

NDF2FITS now uses the NDG library to allow conversion of NDFs stored as sub-components within an HDS container file (e.g. scuba data, etc).

IRAF release V2.11.3 libraries are used in this release for building NDF2IRAF and IRAF2NDF.

This document has been updated to describe the new applications and enhancements, and to include the `IRAF Versions' section. Early release-note sections have been removed. On installation, only a link to the installed L^ATEX document is now retained in the source directory.
