I am wondering why f/sigf is always about twice of i/sigi. Is there any mathematics behind this relation? Maybe it is not directly related to phenix, but i sincerely hope someone could help me with it.
I don't know the logic behind this, but from notes in our code, the default implementation appears to be this one: http://www.iucr.org/__data/iucr/cif/software/xtal/xtal372htmlman/html/addref... specifically, section 4.5.2.4. -Nat
