The majority of the programs on this site have been written in our group although the number of donated programs is on the increase. Our programs are often based on preceding older code, for which I tried to acknowledge authorship when known. This is nevertheless not taken too far, as coding is, on the whole, rather conservative. With some exceptions mice and GUI's are studiously ignored. The several graphics programs are keycode operated, although help screens are available.
All programs contain extensive descriptive headers in the listings.
In keeping with the tradition of this field I assumed implicit consent of the original authors to such action. If this is not the case then please let me know. Several programs written by other people have had internal workings unaltered, while changes have been made to input, output, and commenting in the listing. Making these programs available publicly is a way of paying my debt to the many predecessors in programming for rotational spectroscopy from whose code I have been able to draw freely. I would be happy to accept programs to add to this site on a deposited basis.
