SLALIB is descended from a package of routines written
for the AAO 16-bit minicomputers
in the mid-1970s. 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).
