darkplotter 1.0.3

Dark Plotter
Dark Plotter is a Python package for visualizing velocity as a function of radius for the Milky Way galaxy in an interactive way. This Python package was developed as a project for the Code/Astro workshop in 2024. Code/Astro 2024
The study of the orbital velocity of the galactic disk has provided astronomers with insights into the nature of dark matter, a substance that is so far not well understood, despite composing approximately one-third of the universal energy density. The equations of gravity, both classic and relativistic, fail to explain why galactic rotation curves do not decay as quickly as we expect they should with increasing distance from the core. Mathematical models to describe the gravitational potential profiles for galaxies as a function of radius, including the Navarro-Frenk-White, Plummer, Hernquist, and Jaffe profiles offer different perspectives on a galaxy's mass and velocity distribution. However, researchers and students often face challenges in visualizing and comparing these models with observed data, emphasizing the need for an interactive tool to aid in the teaching and exploration of galactic dynamics. This tool enables the direct comparison of the observed Milky Way velocity profile with the included models.

Getting Started
Prerequisites
Before using this program, you'll need the following:

Python 3.10 or higher installed on your system.
Jupyter notebook.

Installation
You can install Dark Plotter on Windows, MacOS, and Linux distributions. In either case, we assume that you have already installed the dependencies and the appropriate Python version. There are two options to install Dark Plotter:
GitHub
You can install the latest sources from Dark Plotter by cloning the repository directly from GitHub:
git clone https://github.com/brettonsimpson/darkplotter
cd darkplotter
pip install darkplotter

Or, instead, use pip with the path to the repository:
pip install darkplotter@git+https://github.com/brettonsimpson/darkplotter

PyPI
A stable compiled version of Dark Plotter is available on PyPI. You can install it by running:
pip install darkplotter

Testing
If you have installed the development version of Dark Plotter or cloned the complete source code (e.g., from the GitHub repository), you can run the tests by executing the following commands:
cd darkplotter
python -m unittest -v

Usage

Open Jupyter notebook.

Import the darkplotter :

import darkplotter

Use the plot function to create the interactive rotation curve plots.

DarkPlotter.plot()
