Dear Mike, I am not sure what you mean by 'reference'. When you multiply your data with exp(-Bs^2) with B > 0 you weight your reflections depending on resolution so that high resolution data (probably including noise) are supressed while low resolution data a underlined. Using the term 'B' with its relationship to the ADPs is probably only a way to make it sound more fancy.
You can call this textbook knowledge, maybe that's why there is not a real reference?
