The coming of the VAX +allowed a much more comprehensive and thorough package +to be designed for Starlink, especially important +at a time when the adoption +of the IAU 1976 resolutions meant that astronomers +would have to cope with a mixture of reference frames, +timescales and nomenclature. +<P> +Much of the preparatory work on SLALIB was done by +Althea Wilkinson of Manchester University. +During its development, +Andrew Murray, +Catherine Hohenkerk, +Andrew Sinclair, +Bernard Yallop +and +Brian Emerson of Her Majesty's Nautical Almanac Office were consulted +on many occasions; their advice was indispensable. +I am especially grateful to +Catherine Hohenkerk +for supplying preprints of papers, and test data. A number of +enhancements to SLALIB were at the suggestion of +Russell Owen, University of Washington, +the late Phil Hill, St Andrews University, +Bill Vacca, JILA, Boulder and +Ron Maddalena, NRAO. +Mark Calabretta, CSIRO Radiophysics, Sydney supplied changes to suit Convex. +I am indebted to Derek Jones (RGO) for introducing me to the +``universal variables'' method of calculating orbits. +<P> +The first C version of SLALIB was a hand-coded transcription +of the Starlink Fortran version carried out by +Steve Eaton (University of Leeds) in the course of +MSc work. This was later +enhanced by John Straede (AAO) and Martin Shepherd (Caltech). +The current C SLALIB is a complete rewrite by the present author and +includes a comprehensive validation suite. +Additional comments on the C version came from Bob Payne (NRAO) and +Jeremy Bailey (AAO). +<P> +<BR> <HR> +<A NAME="tex2html353" HREF="node12.html"> +<IMG WIDTH="37" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="next" SRC="next_motif.gif"></A> +<A NAME="tex2html351" HREF="node2.html"> +<IMG WIDTH="26" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="up" SRC="up_motif.gif"></A> +<A NAME="tex2html347" HREF="node10.html"> +<IMG WIDTH="63" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="previous" SRC="previous_motif.gif"></A> <A HREF="sun67.html#stardoccontents"><IMG ALIGN="BOTTOM" BORDER="0" + SRC="contents_motif.gif"></A> +<BR> +<B> Next:</B> <A NAME="tex2html354" HREF="node12.html">LINKING</A> +<BR> +<B>Up:</B> <A NAME="tex2html352" HREF="node2.html">INTRODUCTION</A> +<BR> +<B> Previous:</B> <A NAME="tex2html348" HREF="node10.html">New Functions</A> +<BR> <HR> <P> +<P><!--End of Navigation Panel--> +<ADDRESS> +<I>SLALIB --- Positional Astronomy Library<BR>Starlink User Note 67<BR>P.
