The waveforms are measured with a particular load.  As I recall, 
that load is stated in "R_fixture", "C_fixture", "L_fixture", 
and "V_fixture".  If you have only one table of a particular 
kind (rising or falling) anything that generates that waveform 
into that load is valid.  If you have two or more, the combined 
information is used to refine the dynamic impedance.

One way to handle C_comp is to add it to C_fixture, which in 
effect de-embeds it, then explicitly add the capacitor.
