[sdpd] Anomalous/unindexed patterns in a series

["Stuart Atkinson" <Stuart...@astecwaste.com>]

Hello,

I am looking for examples of series of generic compounds where there appear to be anomalies in the powder data. For example:

(i) a series of compounds where almost all patterns index on the same cells, yet there are a few that remain unindexed. An example is the series of compounds NaLnF4 - all are cubic or hexagonal yet there is one unindexed entry (JCPDS ref 10-0123 NaCeF4).

(ii) a series of compounds where the vast majority index on the same cell, yet there are a few of another cell.
