Subject: [EXTERNAL] Update on Scale Factor

Hello All,

For computing scale factor, I used splines interpolation (as Hao Jiang from USC) and below plot is the result (x-axis is Missing Mass Square).

First, I used splines polynomials to fit carbon at specific x intervals. The, I used that splines polynomials + gaussian to fit butanol.
While fitting the butanol using the carbon splines polynomials, it gives out the how much the splines polynomials need to be scaled to make a good fit on butanol, which I can use as the scale factor.

The plot is a result of only one of a energy + angle bin, and it yet doesn't work on all energy/angle bins. I now will use least square minimization to see if this method works on all bins..
Please let me know what you think.

Thank you,
Chan
