Background Analysis

In order to find the SNR at [math]\displaystyle{ t_{Beam Off} }[/math], the background was analyzed to check if it remained constant from [math]\displaystyle{ t_{Beam Off} }[/math] until [math]\displaystyle{ t_{Measure} }[/math]. First, the background was plotted for each concentration of Se/Soil and was overlaid with the the background in the pure sample for each respective target.
