What is it about?
In this paper. authors given a new new figure of merit function for crystal structure determination, Rtian, which was deduced from pseudo-atom scatting factor and oberved structure factor. With this new FOM function, the crystal structure could be determined with non-atomic resolution data (about 2.0~2.2 A for light atoms, and 2.5A for heavy atoms)

Why is it important?
This new FOM function will play a key role in structure determination.
