For a Lebail extraction using Fullprof - JLKH=1 is used.
Having found this out in hindsight, does anyone know what
JLKH=0 is supposed to be doing as I can't find a reference
in the manual to JLKH=0.  It somehow seems to be appending 
information/HKLs to the *.HKL and *.FOU as shown below.
This occurs when performing multiple cycles to gradually 
improve the profile fit.
Thanks in advance,
Lachlan.
