\textbf{Figure 8}  \end{centering}  \par Franck-Hertz curve recorded for Argon atoms. "V" is the measured anode current, converted to an output voltage using a current preamplifier. This The  graph shows how  the changing of background data was removed from  the mercury data. The initial curve.The  blue line is the actual Mercury collected Argon  data, the green orange  line shows the quadratic fit of the original Mercury collected Argon  data, and the orange line is the original Mercury "true" Argon  data with the quadratic fit subtracted. without background.
