JWST Data Analysis Visualization Tool
Content Migration
WARNING: This page has been deprecated and the content migrated to Jdaviz Tutorials. Please update your links accordingly.
The JWST Data Analysis Visualization (Jdaviz) tool is a specific component of the broader analysis tool ecosystem designed to work seamlessly with Astropy within a Jupyter notebook. The visualization tools also may be operated as standalone desktop applications or as embedded windows within a website.†

tools or package parameters.
The tool currently has 4 configurations:
- Imviz is a 2-D image viewer.
- Specviz is a tool for visualization and quick-look analysis of 1-D astronomical spectra.
- Cubeviz provides access to and manipulation of spectroscopic data cubes (like those produced by JWST MIRI MRS or NIRSpec IFU), along with 1-D spectra extractions from the cube.
- Mosviz is a visualization tool for viewing multi-object spectrograph data (e.g., JWST NIRSpec MOS mode), and includes viewers for 2-D and 1-D spectra as well as contextual information like on-sky views of the spectrograph slit.
The Jdaviz tools have demonstration videos available on the JWST Observer YouTube channel.
Imviz video demos | ||
Length | Description | |
|---|---|---|
| 1:59 | Opening Image Data: This video is the first in a series of beginner tutorial videos on Imviz. It will demonstrate how to open imaging data in Imviz. | |
| 1:24 | Overplotting a Catalog: This video is the second in a series of beginner tutorial videos on Imviz. It will demonstrate a common practice of overplotting markers corresponding to a catalog, in this instance the photometry catalog output from the JWST pipeline. | |
| 1:36 | Aligning Images: This video is the third in a series of beginner tutorial videos on Imviz. It will demonstrate how to open 2 images side-by-side in 2 separate windows and link them by WCS. | |
| 1:50 | Exploring the Plugin Toolbar: This video is the fourth in a series of beginner tutorial videos on Imviz. It will demonstrate how to interact with the data using the tool itself, as opposed to using the notebook. | |
| 3:45 | Aperture Photometry: This video is the fifth, and last, in a series of beginner tutorial videos on Imviz. It will demonstrate how to perform aperture photometry. | |
Specviz video demos | ||
Length | Description | |
| 2:24 | Open a Spectrum: This video is the first in a series of beginner tutorial videos on Specviz. It will demonstrate how to open a spectrum in Specviz. | |
| 1:58 | Model Fitting: This video is the second in a series of beginner tutorial videos on Specviz. It will demonstrate how to define spectral subsets for model fitting. In this case, the goal is to fit a background continuum model. | |
| 3:10 | Line Analysis: This video is the third in a series of beginner tutorial videos on Specviz. It will first demonstrate how to subtract a model from a spectrum. In this case, the goal is to subtract a background continuum model. Then it will show how to analyze a background-subtracted spectral line within the tool, including the flux, equivalent width, and redshift. | |
