The following automatic conversions were performed:

'_refine_ls_weighting_scheme' value 'w=1/[\s^2^(F~o~)^2^+(0.127P)^2^
+0.2421P] where P=(F~o~^2^+2F~c~^2^)/3' was changed to 'calc'. New
tag '_refine_ls_weighting_details' was created. The value of the new
tag was set to 'w=1/[\s^2^(F~o~)^2^+(0.127P)^2^ +0.2421P] where
P=(F~o~^2^+2F~c~^2^)/3'.
