[sdpd] UPPW-1

[Armel Le Bail <alb...@cristal.org>]

Hi,

A new service starts at the SDPD mailing list, the UPPW :
              Unindexed Powder Pattern of the Week

Every week, a problem to solve will be proposed, you can
send solutions at uppw...@cristal.org (provide the software
name, the cell, the M20 and F20 figures of merit and more if
you wish). These solutions, if any, will be summarized at the
SDPD mailing list the next week, while a new problem will be
offered. Anonymity will be ensured, unless the contrary is
specified.


UPPW-1 :

ICDD 49-2190
C14H9NO4 - 3-Amino-alizarin
ICDD Grant-in-Aid (1997)
"Any unindexed patterns require special justification to be
accepted in the PDF. In particular, strong evidence of phase
purity would be essential"

If you possess an unindexed powder pattern and wish it to
be proposed as an UPPW, preferably send it to uppw...@cristal.org
either as a list of d(A) (or 2-theta) and I values or as a digitized
pattern. Your problem will be queued ;-).

Best wishes,

Armel
