Click the right mouse button with the cursor over a window title.
To exit the menu, click the central mouse button, or both buttons.
One of the options is to make a table, where you can see how the
values change for several modes.

The three frequencies are for the assembled system. The program lists
the three w0^2LC products too. You can obtain the three frequencies for
the disconnected system from them:
If w0^2*L*C=x, then f = 1/(2*pi*sqrt(L*C)) = w0/(2*pi*x).
The program mrn6 lists the resonances for the system assembled and
disassembled if you check the "list detais" box and plot the curves.
