# Document Method Comparison
This skill provides a procedure for creating educational sections in Jupyter Notebooks that compare two or more methods (e.g., `gwpy` vs `gwexpy`).
## Instructions
1. **Technical Analysis**:
* Examine the source code of both methods to identify implementation differences.
- **Averaging/Integration**: Does it downsample the data using a sliding window? (e.g., `gwpy.heterodyne`)
- **Filtering**: Does it use a Low-Pass Filter (LPF) like Butterworth or FIR? (e.g., `gwexpy.lock_in`)
* Compare numerical characteristics like time resolution and frequency response (aliasing).
2. **Physical/Conceptual Context**:
* Check if there are differences between engineering definitions and package conventions.
- Example: `gwpy.heterodyne` effectively performing "Homodyne" detection relative to the carrier frequency.
* Identify the target use case for each (e.g., stationary signal vs transient analysis).
3. **Construct Comparative Sample Code**:
* Create a synthetic signal that highlights the differences (e.g., a signal with rapid amplitude/phase changes).
* Execute both methods on the same input signal with comparable parameters (e.g., matching the averaging stride with the filter bandwidth).
* Visualize results in a single plot for direct comparison.
- Use `plt.step(..., where='post')` for discrete averaged data.
- Use `plt.plot(...)` for continuous filtered data.
4. **Draft Markdown Explanation**:
* Use tables to summarize differences (Algorithm, Resolution, Post-Processing, Features).
* Provide a clear summary statement on "which method to choose" for specific user goals (e.g., "Use `.lock_in()` for control system transient response").
5. **Integration**:
* Use Python scripts to inject these cells (Markdown and Code) into the target `.ipynb` file, typically appending to the end or inserting into a relevant section.
