\begin{centering}  \textbf{Figure 6}  \end{centering}   \par Franck-Hertz curve recorded for Mercury atoms at a single temperature. Again "V" is the measured anode current, converted to an output voltage using a current preamplifier. The graph shows how the background data was removed from the initi al initial  curve.The blue line is the collected Mercury data, the green line shows the quadratic fit of the collected Mercury data, and the orange line is the "true" Mercury data without background.
