About

The Explorer is SDSS-V's interface for accessing and exploring Milky Way Mapper stellar parameters provided by Astra for SDSS-V targets. The Explorer is designed to provide a high-speed interface for aggregated statistics and visualizations of filtered Subsets of the SDSS-V database.

Explorer is developed by SDSS-V, using solara, fastapi,vaex, and bokeh. Explorer was developed and designed by Riley Thai, and is maintained by the SDSS-V Data Visualization Team.

Note

The examples and screenshots in these docs may reference the best Astra summary catalog file. In SDSS DR19, this file was renamed to mwmLite. In the live dashboard for DR19 you will see reference to the mwmlite dataset. This is the same as best in this documentation. In all data releases DR20 and above, the mwmLite file has been deprecated and removed.

Get started with our examples:

• Example: creating a HR diagram
• Example: selecting sources from Gaia
