The CAT subroutine library is far from being all my own work. Its specification evolved during extensive discussions with (alphabetically) Dave Giaretta, Clive Page, Rodney Warren-Smith and Alan Wood, all of whom have contributed substantially to its final form. Also, at various times, Brian Read, Malcolm Currie and Steven Beard have made useful comments.

Clive Page wrote the expression parser which CAT uses and Appendix  is based on documentation which he supplied. CAT accesses FITS tables through Bill Pence's FITSIO subroutine library and CHI/HDS catalogues through Alan Wood's CHI subroutine library.

Martin Bly assisted in preparing the Unix version for release. Alan Wood, Malcolm Currie and Peter Draper tested a pre-release version and suggested several useful improvements.

I am grateful to all these people for sharing their time and expertise.
