The current version of TTBOX handles different phases by special phase specific code
which is located in MKX4P, MKTIM4P, and MKSMARTTAKEOFF. This is not very elegant, but
easy to implement. MKPHASECATALOG tells you which phases are available.
Future versions, hopefully, will have a more versatile phase name parser.
An exception are depth phases, which are handled recursively by combining an upgoint p or s ray with a standard phase for a surface focus. So every phase TBOX can handle is available as depth phase automatically.
The nomenclature used is a simplified standard nomenclature. The following table summarizes the available symbols and their meaning.
Symbol | Explanation |
---|---|
P | P wave leg |
S | S wave leg |
p | Depth phases: the P leg which goes upward from the source. |
s | Depth phases: the S leg which goes upward from the source. |
K | Outer core P wave leg |
I | Inner core P wave leg |
c | Reflection at Core Mantle Boundary |
i | Reflection at Inner Core Boundary |
