Question: Extract values from list

Hi Maple friends,

Im new to Maple and Im struggeling with a problem.

I have the numbers of a bode plot (abs and phase) and I want to fit it in an equivalent circuit.

My problem is: I firstly want to calculate the real and imaginary part of the measured impedance of the bode plot (This works so far after a few hours of trying) and then I want wo calculate the values for each equivalent circuit component. For that I need the values of the impedance calculation to further process them.

The problem is: The impedance calculation returns the values as a list (I think). So Im wondering how can I get the values out of the list? My code so far is attached below.

Thanks in advance!

PS: Im sorry for the layout of the code. Im not sure how I can format the code right.
