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?
Best,
Tim
