Initially the fits file was loaded into python, the image was then projected onto the xaxis to obtain a spectrum. This was in the units of N_{adu} against position, so from the eqaution N_{pe} = 2.3*N_{adu} the data was plotted in N_{pe} against position.
To calculate the background of the data, the position between 350 and 500 was selected, this have a plot of which had a bright pixel as shown,
mean = 149775.0, stdev = 20571.1, however for a poisson distribution where, f(n,l) = (l^n)( e^{l})/(n!) l is equal to the expextation value and the variance, therefore for the distribution to be poisson the mean should be equal to the square of the standard deviation.
