In GSAS, structure factors extraction is done by starting
from a dummy atom for the calculation of the first |Fcalc| values,
rather than to use all starting |Fcalc| arbitrarily equals which are
then iterated by using the Rietveld decomposition formula (as
in ARIT, WinMprof, FULLPROF, EXTRA, EXTRACT...).
See the Rietveld mailing list old archives at :
http://www.cristal.org/forum/rietveld_l/index.html
and use 'GSAS Le Bail' as keywords for the search.
