Hi all, SRM 676a consisted of Baikowski CR1. This material is of a non-ideal crystallite size distribution: quite broad with tales to large crystallites. SRM 676b was custom made for us by Baikowski with a more uniform crystallite size distribution in the 200 nm region. We are working on the certification, rather complex, see: doi:10.1107/S0108767311014565 . It seems that modern beamlines don't favor the large specimen size needed for our experiments. We have good data from one source, we are looking for some from another as we like to see results from more one machine.

Scale factors and cell parameters found to be within the errors. Profile shape shows similar features (also not an ideal material).
