   As far as I was aware the software (more extensive than Cromer and 
Liberman's code) used to calculate the f' and f'' values given in 
International Tables Volume C is not public domain. From an exchange of 
e-mails a few years ago, I had the impression that the author of the 
software had no intention at that time of releasing them into the public 
domain. Perhaps Syd would like to make a diplomatic representation to 
the person concerned to see if he has changed his mind.

   The person concerned is Jeremy Cockcroft, and he and Paul are now in 
the Chemistry Department of University College London. For the moment 
the e-mail addresses are still the Birkbeck ones.

   If you permit it, I will make representation to Yvon Le Page to see 
if he and NRC will allow the IUCr to host a version of his most 
interesting OBLIQUE programme. He does not release the software and his 
server often needs rebooting.
