phaseRequest

This generates requests based on the times relative to calculated phase arrivals. See the documentation for the TauP Toolkit, http://www.seis.sc.edu/TauP for the phase naming convention. SOD uses the TauP Toolkit internally. The begin and end phase can be a comma separated list. If there are multiple arrivals for the phases, then the time will be calculated relative to the first arriving phase. If there are zero arrivals for the phases, then no request will be generated and no data will be retrieved. The phase name "origin" may be used to express an offset from the origin time.

Example

<phaseRequest>
  <beginPhase>ttp</beginPhase>
  <beginOffset>
      <unit>SECOND</unit>
      <value>-60</value>
  </beginOffset>
  <endPhase>ttp</endPhase>
  <endOffset>
      <unit>SECOND</unit>
      <value>360</value>
  </endOffset>
</phaseRequest>
