TauP Create

TauP Create takes a ASCII velocity model file, samples the model and saves the tau model to a binary file. The output file holds all information about the model and need only be computed once. It is used by all of the other tools. There are several parameters controlling the density of sampling. Their values can be set with properties. See section Default Parameters.

Note that the use of TauP Create is no longer required as the various tools can read velocity models directly and effectively call TauP Create internally. However, if a model file will be used repeatedly, using a precomputed .taup file is more efficient.

modelfile is the ASCII text file holding the velocity model. The --nd format is preferred because the depths, and thus identities, of the major internal boundaries can be unambiguously determined, making phase name parsing easier. For compatiblity, we support the --tvel format currently used by the latest ttimes package, Kennett et al. [KEB95].

The output will be a file named after the name of the velocity file, followed by .taup. For example

taup create -nd mymodel.nd

produces the file mymodel.taup which can be used later like:

taup time --mod mymodel.taup --deg 35 -p P,S

The usage is:

Usage: taup create [--debug] [--help] [--verbose] [--prop=<toolPropsFilename>]
                   ([--mod=<modelName>] | --nd=<nDModelFilename> |
                   --tvel=<tvelModelFilename>)
Create .taup file from a velocity model.

Options:

      --debug     enable debugging output
      --help      display this help message
      --prop=<toolPropsFilename>
                  load defaults from properties file
      --verbose   enable verbose output
Velocity Model
      --mod, --model=<modelName>
                  use velocity model "modelname" for calculations, format is
                    guessed. Default is iasp91.
      --nd=<nDModelFilename>
                  "named discontinuities" velocity file
      --tvel=<tvelModelFilename>
                  ".tvel" velocity file, ala ttimes
