Calculation of the tangential Efield integral along a base line using IMSAFE.

Hello,
To calculate the tangential Efield integral along a wire using IMSAFE, I extracted the tangential Efield along 10 random splines using 10 disks (the radius of the disks are the same as the radius of the wire) in a text file. To calculate the integration of the tangential Efield along the baseline, I calculate tangentialcomponent magnitude as "E_T = Sqrt((realtangentcomp)^2+(imagtangentcomp)^2)" and then I calculate "Sum(distalongline. E_T)" for each line. Then I average over the values for 10 random lines to get the value of the integration of tangential Efield along the base line. Is that a correct procedure?
Thanks.
