We plotted the new hypothesis mean = mean0 + mu*t , however since our data was all over the place we used the last years dark frames that were at a constant temp 5 degrees which is much better that the -15 degrees. below is the graph of both those tempratures

This is -5 degrees

This is -15 degrees

The same thing was done with the new sigma fit sigma = sqrt(mu*t + simga_0)

temp 5 degrees

temp -15 degree
