Pole position has become a new important parameter to describe the properties of nucleon resonance. Compared to the Breit-Wigner parameters, the pole position is less model dependent. The shape of resonance based on our previous formalism is strongly affected by the hadronic form factors. We study the effect of different background parameters on the extracted pole position. We have also used different hadronic form factors to see the effect on the background dependence of pole position. We obtained the necessary parameters by fitting to about 9000 experimental data points. We expect to find appropriate hadronic form factors that lead to the background independence. Therefore, this study will shed a light on the choice of the appropriate hadronic form factors.
