Plasma diagnostics (plasmapy.diagnostics)

Introduction

The diagnostics subpackage contains tools for experimental research. Currently, we have functionality for analyzing data from Langmuir probes located in plasmapy.diagnostics.langmuir.

Examples:

• Langmuir probe data analysis

Reference/API

plasmapy.diagnostics.langmuir Module

Defines the Langmuir analysis module as part of the diagnostics package.
