This script **estimates** the buffer scale factor using the 1-D scattering curves from SAXSLab 1-D process: "*.dat" files.
This is based on the assumption that the extended scattering follows Porod's Law: I(q) ~I/q^{4}.
The optimal scale is determined in an iterative process, so be patient.
It takes several seconds for the process to converge.

Select the SAXSLab "sample*.dat" file**

(1) Sample Data *.DAT:

(2) Buffer Data *.DAT:

Minimum value of q to use in Porod Estimation:
^{-1}

(Only use data >> 1/Rg: Exclude major features in data, such as the first peak):

A q_{min} in the range 0.20 - 0.30 Å^{-1}seems to work well.
