Well, Linda Devito sent out a mail message on Friday to a bunch of people
which contained most of this information. I looked at the list of recipients
for that message and for some reason your name wasn't on the list, so
here is a copy:

I've just checked these PVs and they do seem to exist.
Hope this helps,
