The final tab which both the integration and intensity sweeps finish on is the results tab:Here all the results for the pixels are presented in histograms, if it is an intensity sweep the darkcurrents histogram is blanked out. You then have the option to save the results in 2 txt files:Results.txt: this contains the per pixel results used to make the histogramsPlots.txt: this contains the plots where each point is the average from all the pixels.The program calculates variances by the equationVar = - 2Noise is calculated differently for each sweep type:Intensity sweep: (Sqrt(dark variance))/K(with K in DN/e)Integration sweep: Dark variance from the intercept <strong>of</strong> the Dark variance graph square rooted andthen divided by the gain.96
