[GSAS-II] Axial Divergence Problem

[maykel manawan]

Dear all,

I had a strange peak at lower angle (003, ~22 2theta) collected from LiCoO2 (R -3 m).
It's a single phase powder diffraction and only one peak as in ICSD database 2013.
The peak getting more unreasonable as I heated, (but it still single phase)

Please take a look the profiles: LiCoO2-003.JPG

I tried to use S/L in GSAS-II but the value is not reasonable S/L > 0.177570E-01 (L=173mm).
Thanks for the attention.
