This page describes the format for the files used in Broadband Platform Simulations. The simple source description (SRC file) and the station list (STL file) are inputs to the Broadband Platform simulations, and must be provided for every run. The velocity model file is part of a velocity model configuration package and is also an input to the platform. A single velocity model file can be shared among several simulations using the same region. The time history (BBP) file is produced by the Platform. The Broadband Platform workflow description (XML file) is an intermediate product of the Broadband Platform. It is produced automatically by the Platform, but can also be provided by the user in cases where script automation can be used to replace the interactive prompts of the Platform.
