Compute and generate theo phases

command: THEOPHASE <method> <trclist> [<phaselist>] [<origintime>] [<epilat>] [<epilon>] [<srcdepth>]

Compute theoretical phases at traces specified.

parameters

  • <method> parameter type: string
    Computation method. Possible values are 'local' (model: layer over halfspace, for local phases) and 'taupi' (obspy.taup, for teleseismic phases).
  • <trclist> parameter type: trace list
    List of traces where to compute theoretical travel times.
  • <phaselist> parameter type: string
    Comma separated list of phases to compute on each trace/station. If necessary switch off automatic cap conversion of the command parser ("switch capcnv off"). If not specified taken from SHX variable 'phaselist'.
  • <origintime> parameter type: string
    Origin time of event. If not specified taken from SHX variable 'origin_time'.
  • <epilat> parameter type: float
    Latitude (in deg) of event epicenter. If not specified taken from SHX variable 'epi_latitude'.
  • <epilon> parameter type: float
    Longitude (in deg) of event epicenter. If not specified taken from SHX variable 'epi_longitude'.
  • <srcdepth> parameter type: float
    Source depth in km. If not specified taken from SHX variable 'source_depth'.

qualifiers

  • /MODEL
    Specify velocity model. For 'taupi' look in obspy documentation for details (default: 'iasp91'). For 'local' specify two layer model.

example

@THEOPHASE LOCAL ALL Pg,Sg,Pn,Sn
Compute local theoretical phases on all traces and takes origin info from SHX variables. Computed phases are plotted in green color.
