compoundPhaseSignalToNoise

This calculates the signal to noise ratio (short/long) in the time window described by the offsets around the given phases and passes if the ratio is less than the given ratio. See the documentation for the TauP Toolkit, http://www.seis.sc.edu/TauP for the phase naming convention. SOD uses the TauP Toolkit internally.

Example 

<compoundPhaseSignalToNoise>
    <phaseName>SKS</phaseName>
    <shortOffsetBegin>
        <unit>SECOND</unit>
        <value>-5</value>
    </shortOffsetBegin>
    <shortOffsetEnd>
        <unit>SECOND</unit>
        <value>5</value>
    </shortOffsetEnd>
    <longPhaseName>ttp</longPhaseName>
    <longOffsetBegin>
        <unit>SECOND</unit>
        <value>-105</value>
    </longOffsetBegin>
    <longOffsetEnd>
        <unit>SECOND</unit>
        <value>-5</value>
    </longOffsetEnd>
    <ratio>2.5</ratio>
</compoundPhaseSignalToNoise>
