Due to the dynamic development environment and effort required to remake videos, you might see small differences between the displays in some help videos relative to the released versions of the tools. Most of the help provided in these videos is general in nature and does not depend on specific tool versions. If you notice any serious problems related to software versions that result in the presentation of incorrect information, please help us by contacting the JWST Help Desk.

Table 1, below, contains links to data analysis tool help videos that have been posted to the JWST Observer YouTube channel.

Links to many of these video help tutorials are placed directly into many individual articles where it is relevant. For a visual clue, look for the JWST video icon: 



YouTube features

For the YouTube videos, users should be aware of some nice features provided by the controls at the lower right corner of the video window. These include the ability to go to full screen (to better see details), the "CC" button, which provides automatic closed captioning of the audio stream, and the Setting-Quality option, that permits the user to control the resolution and file size that fits their needs. Controls at lower left allow the user to start and stop the video and mute the sound if needed.


Master list of JWST data analysis tool videos

Table 1 lists the video tutorial help available in support of JWST data analysis tools along with short descriptions for each video. Links on the video titles in the first column will connect you to each video directly. 

Note: the JWST Observer YouTube channel also hosts webinars, recorded JWST town halls from AAS meetings, and other recordings not listed here. When you go to the JWST Observer channel, be sure to subscribe to it to see updates.


Table 1. Videos on JWST data analysis tools

Imviz video demos


Length

Description
1:59Opening 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.
1:24Overplotting 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.
1:36Aligning Images: This video is the third in a series of beginner tutorial videos on Imviz. It will demonstrate how to open two images side-by-side in two separate windows and link them by WCS.
1:50Exploring 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.
3:45Aperture 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
2:24Open 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.
1:58Model 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.
3:10Line 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.

Cubeviz video demos


Length

Description
2:43Open and Explore a Cube: This video is the first in a series of beginner tutorial videos on Cubeviz. It will demonstrate how to open an IFU data set and explore a 3D data cube.
2:36Selecting Subsets: This video is the second in a series of beginner tutorial videos on Cubeviz. It will demonstrate how to define both spatial and spectral regions to allow for the analysis of specific subsets of a data cube.
3:00Model Fitting: This video is the third in a series of beginner tutorial videos on Cubeviz. It will demonstrate how to fit a model to every spaxel within the data cube. In this case, the goal is to fit a background continuum.
3:30Line Analysis: This video is the fourth in a series of beginner tutorial videos on Cubeviz. It will first demonstrate how to subtract a model cube from the original data cube. 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.
