Core Module (pysit.core)

Introduction

The pysit.core package provides the general tools necessary to setup a seismic inversion experiment, including:

• The description of the physical domain (pysit.core.domain) in physical coordinate
• The description of the computational mesh (pysit.core.mesh)
• Source profile functions (pysit.core.wave_source)

• Data acquisition (pysit.core.acquisition), including:

  • Sources (pysit.core.sources)
  • Receiver (pysit.core.receivers)
  • Shots (pysit.core.shot), which are source and receiver pairings
  • and their respective representations on computational grids (pysit.core.mesh_representation)

Components of pysit.core

• Domain (pysit.core.domain)
• Mesh (pysit.core.mesh)
• Wave Sources (pysit.core.wave_source)
• Acquisition (pysit.core.acquisition)
• Shot (pysit.core.shot)
• Sources (pysit.core.sources)
• Receivers (pysit.core.receivers)
• Mesh Representation (pysit.core.mesh_representation)
• Acquisition (pysit.core.acquisition)
