I am sorry for disturbing you all again, since I am self learning to fit multiple scattering for biogenic Mn oxides in Artemis, I am quite lost in understanding the basics of Mn Mn corner sharing path. 

All reports are included Mn-Mn Corner at ~ 3.4 A, which I cannot find in my Feff calcuation for Phyllomanganate layer (Na-Birnessite) model. Below are the crystallographic information of Na birnessite I used (also available in the attachment), Na is excluded.

A = 5.174 B = 2.850 C = 7.336 and angles 90, 103.18 and 90 for alpha, beta, gamma respectively

Parameters

                                  X              Y                Z

             Mn                 0              0                0

              O1            0.37600         0            0.1330

I have two questions 

1) How to identify the Mn Mn corner paths from the Paths result.

2) Where can I find the Coordination Number for Mn Mn Corner, If i see in eg. Webb et al., 2005 (http://www.intl-ammin.geoscienceworld.org/content/90/8-9/1342.short)  the CN numbers for Mn-Mn Corner is 0.6(1.0) or 0.8(8), what does the number represent in the brackets?

It will be looking forward for your help.

Regards
