Basic Search for Observations
After you search for JWST observations following the guide in Basic Data Search, the Jda icon will appear next to relevant search results that you can view in Jdaviz (see Figure 1). This icon indicates that the row result contains data products that can be loaded into the Jdaviz web display.
Clicking the Visualize Spectra (Jda) icon produces a drop-down menu with two available options, see Figure 2.
The available dropdown options are:
- Display default Minimum Recommended Product (MRP) - opens the default Minimum Recommended Product for the selected observation in the Jdaviz quicklook spectra page. See Viewing Spectra and Images for more.
- Search through other data products related to this observation - opens a new page containing all relevant data products associated with the selected Observation that can be loaded into Jdaviz. See Finding Associated Data Products for more.
Science Instrument (SI) Search for Observations
After performing a search for JWST observations following the guide in Science Instrument (SI) Search , a new icon will appear for search results that can be viewed in Jdaviz (see Figure 3). Each row result represents a single JWST data product. Which icon is displayed in each row depends on the type of data product in that row. See Icon Nomenclature below for the meaning of each icon.
Loading Known Data by URI
Rather than performing a search, if you already know the URI (for MAST products, the "dataURL") of the data product, you can visit the page directly.
The direct URL for the Jdaviz quicklook page is It requires one of two query arguments to successfully load a spectrum, either the uri or filename query argument. Inputting this into the search bar will navigate you to the appropriate page. Figure 4 shows an example of a spectrum loaded into the specviz module.
Alternatively, you can navigate to your page directly using the syntax "]", or similarly using the syntax "https://mast.stsci.edu/viz/ui/#/spectra?filename=jw01409-o133_t011_nirspec_prism-clear_x1d.fits.]". For example, you might navigate directly to
