Hi Peter,
Sorry, I can't check at the moment - I gifted my collection of AES
Journals (back to 1975 and a few before that) to the Uni when I retired and
I don't have a current subscription to the AES library (only tend to be
prepared for one when I'm doing research) AND the old memory cells seem to
have lost the info :-(
