[Ifeffit] delR versus thermal expansion A and first cumulant C1*

[Leandro Langie Araujo]

Hi, that's me again....
but with a shorter message this time.

Just when I sent my last message, I realized there was a new message 
from Anatoly in my inbox. And I believe it contains the answers for my 
latest questions! How wonderful it would be if data acquisition/analysis 
was this fast... ;)

So, I'd like to extend my thanks to Anatoly as well, for the 
enlightening reply.

Cheers,
Leandro
