Actually this question is a little more complicated than it appears because there is a possibility that readings of a Stouffer step wedge will result in readings that are different in UV, Visual and Blue mode. If that is indeed the case I would recommend using the new values instead of the default values as appropriate, i.e. values read in UV mode if working with alternative processes, and Blue values if working with silver graded papers.

However, the whole logic of this is not absolutely clear to me so I would be interested in hearing from other BTZS users on this.
