Se170063 Thin Window Analysis

In order to try to pin down the ratio of pure selenium to the selenium in the soil, try using a 2 channel window to find the signal. The error in the signal will be found by standard error propagation in mathematica. Since the max value is fixed, it does not appear in the stats box, but I have included it in the table.
