Tassos,
I'm no expert either, and there are caveats for using this formula on
correlated magnitudes. But I would assume that the intensities of twin related

Dear Fulvio, you cannot detwin perfectly twinned data with this
formula. The term (1-2α) becomes zero, so you are dividing by zero.
With good

Dear Fulvio,
you cannot detwin perfectly twinned data with this formula. The term (1-2α)
becomes zero, so you are dividing by zero. With good refinement programs
(ShelX, Refmac), refinement is done against twinned data, which is better than
to detwin the data with the formula you mention.
As I
