Thanks to those who contributed their ideas and views about the development of CCDPACK. David Berry is thanked for developing the first version of the NDF list access software. Rodney Warren-Smith developed the excellent MAKEMOS application. TRANNDF uses the internals of an early version of the KAPPA application TRANSFORMER written by Malcolm Currie, who has also submitted some improvements to the percentile location routines and helped with testing and bug reports.
The XREDUCE, IDICURS, PAIRNDF and CCDALIGN applications use Tcl/Tk scripting language developed by John Ousterhout, together with the [incr Tcl] extensions by Michael J. McLennan and the Starlink Extensions to Tcl & Tk (SUN186.1).
