Utilities

• The old ASTQDP program has been replaced by a format conversion program called AST2QDP which converts HDS files to QDP format. A procedure called ASTQDP wraps up this format convertor to run QDP using the converted file. This separation of the two facilities makes installation more reliable, and allows the user to make use of their own site's, or even their own personal copy of QDP.
• The AST2XSP program has been updated to write out the new style FITS spectral files and response matrices. These files are much more amenable to user editing than the old format, and being FITS are portable across all architectures on which FITS is supported.
• A two-dimensional image convolution program has been added, called IXCONV. Performs both cyclic and non-cyclic image convolution.
• IMOSAIC now correctly handles image mosaicing near the celestial poles.
