~~~~~~~~~~~~~

The global models *iasp91* and *ak135* and RSTT are available by default without

further configuration.
|
||||
The global Earth velocity models *iasp91* and *ak135* as well as *RSTT*
|
||||
(section :ref:`iloc-velocity_rstt`) are available and applicable by default
|
||||
without further configuration if the default iLoc profile names *iasp91*
|
||||
and *ak135*, respectively, are considered. The same is true if explicit iLoc
|
||||
profiles using *iasp91* or *ak135* for the profile names are added to the iLoc
|
||||
configuration. Any other global model can be added, by explicitly adding an iLoc
|
||||
profile as set out in section :ref:`iloc-setup`. The respective model name is
|
||||
configured in :confval:`iLoc.profile.$name.globalModel`.
|
||||
|
||||
Similar to :ref:`global_locsat` the global models require travel-time tables for
|
||||
each phase which is to be considered. The table files are located in
|
||||
:confval:`iLoc.auxDir`:file:`/[model name]`.
|
||||
|
||||
If available, corrections for Earth's
|
||||
ellipticity are considered from
|
||||
:confval:`iLoc.auxDir`:file:`/[model name]/ELCOR.dat`, e.g.,

||||
:file:`@DATADIR@/iloc/iLocAuxDir/iasp91/ELCOR.dat`.
