Program Hypotable: README
The Hypotable distribution consists of a Unix directory tree
with four sub-directories: ./iaspei-tau, which includes
the software needed to construct the iasp91 traveltime tables
and create the Hypotable executable;
./build-tables, which has the input and output for building a set
of tables in the format to be used in Hypoellipse;
./sample-runs, which gives a sample application showing how these
tables can be used in Hypoellipse; and ./bin, which is empty in the Hypotable distribution but is where the executable files are placed on a Unix system after running the makefiles which create them. Three README HTML files contain information on the contents of ./iaspei-tau, ./build-tables, and ./sample-runs.
There are two files in PC-ZIP formta which can be downloaded:
I do not use PCs, but I succeeded in creating the IASP91 tables for use in my FOCMEC package. However, the tables are compiler dependent and the software is not robust for models other than iasp91, so I have chosen not to provide them here. The
USGS ftp server has
source code and instructions for building the iasp91 software package on a PC.
The source for
Hypotable is written in basic Fortran 77 so should compile on
other platforms with only minor modifications.
