XiP is an interactive plotting tool designed for XSPEC-based spectral analysis. It is used to visualize the effects of different XSPEC models and their parameters by creating interactive plots in Jupyter Notebooks with the help of ipywidgets.

Note: This tool is primarily designed with eROSITA data in mind, but other X-ray data may require some modifications.

• Interactive Plotting: Visualize spectral data, different XSPEC models and residuals interactively using sliders for model parameters.
• Model Configuration: XiP can be run in three modes: src, bkg, and src_bkg, allowing users to configure the source and background models separately or together.
• Parameter Management: Ability to freeze parameters, tie parameters and fit the model using XSPEC's. In src_bkg and bkg modes, users can add filter wheel closed model as vary its normalization

Install all dependencies using the requirements.txt file:

pip install -r requirements.txt

Note: Ensure XSPEC 12.13.1 (PyXspec 2.1.2) or above is installed and properly configured on your system.

Follow the instructions in the XiP_demo.ipynb notebook to configure data and models and plot the spectrum. The notebook provides a step-by-step guide on how to set up the data directory, source and background files, and model parameters.

You can also find a detailed explanation of the internal parameters and their usage on the XiP GitHub Wiki.

Contributions are welcome! Please submit a pull request or open an issue for any bugs or feature requests.

This tool was built because I found it difficult to visualize the effects of different XSPEC models and their parameters.

I hope you find it useful for your spectral analysis needs. If you have any suggestions for improvements or new features, please feel free to reach out at my email id: [email protected].

This tool is a work in progress and may have bugs or limitations. Please report any issues you encounter, and feel free to suggest improvements or new features.
