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 integrating a gaussian over the window and finding the error by expanding sigma by its own error. There seems to be a problem with root's fitting mechanism when I set the amplitude. Even though the max value in the window is given, when trying to set the amplitude to the maximum, the fitter doesn't seem to do that. Below is an example

	400 <t< 640 sec	1100 < t < 1360 sec	1875 < t < 2150	2650 < t < 2930 sec	3400 < t < 3690 sec	4120 < t < 4400 sec	4840 < t < 5130 sec
