Amplitude for Richter Scale

This is a great idea.
My question is that when measuring the
seismographic amplitude for the Richter scale what amplitude do I use?
1. max S-wave amplitude
2. max L-wave amplitude
3. mean S-wave amplitude
4. mean L-wave amplitude
The Richter magnitude is determined by measuring the
amplitude of the largest wave recorded on the
seismogram. If you are looking at a seismogram and the
surface waves are the largest, use the largest one to
determine the magnitude of the quake. If an S-wave is
largest, use that wave. The Richter scale is purely
based on amplitude of the biggest wave, not on what
type of wave it is.
Hope this helps.
