Case Studies (Goal-Oriented Workflows)

Note

Page role: Guide index

A collection of goal-oriented demonstrations that combine multiple GWexpy features into practical workflows. To learn feature-oriented examples first, refer to Tutorials (Feature-Oriented Learning).

Audience: Users who already know the basics and want end-to-end examples mapped to real analysis tasks. Prerequisites: Familiarity with the relevant core classes, especially from Tutorials (Feature-Oriented Learning) and Getting Started. Use this page for: Finding the canonical public gallery of GWexpy goal-oriented case studies by workflow theme. Search hints: case studies, gallery, end-to-end workflow, calibration, interoperability, noise hunting, ML

Note

Case Studies are goal-oriented workflow demonstrations, while Tutorials are feature-oriented class/capability examples. This page is the canonical public index for all case_* notebooks.

Note

On this page: Section I focuses on calibration and control, II on interoperability and reproducibility, III on statistical and ML workflows, and IV on noise hunting and detector diagnostics.

Note

Example framing: Goal: pick a workflow family that matches your task. Inputs: familiarity with the relevant GWexpy objects and the notebook environment. Outputs: a case-study notebook path you can read or run locally.

Featured Gallery

Note

These featured cards reuse the same three teaser thumbnails shown on the homepage. This page remains the canonical gallery: the homepage is a short visual preview, while the full categorized list below is the source of truth.

Noise Budget

Identify dominant couplings and compare mitigation directions in a detector-noise workflow.

Noise Budgeting and Multi-Channel Correlation Analysis

Transfer Function Estimation

Estimate coherence, fit responses, and connect measured transfer paths back to the API.

Tutorial: Transfer Function Measurement

Active Damping

Follow a multi-input multi-output control workflow for a 6-DOF isolation system.
