Data access and analysis

The three main ways to access and analyze Rubin data are the Rubin Science Platform, Alert Brokers, and Independent Data Access Centers.

Rubin Science Platform (RSP)

The RSP is a web-based service for access and analysis of LSST data.

Who can get an RSP account.

• All Rubin data rights holders may create an account and use the RSP.

• Follow these instructions to create a new account.

Which data sets are served via the RSP.

• The Prompt Products Database, including light curves and moving objects.
• The last two annual Data Releases, including observation metadata.

The RSP's three aspects offer a range of functionality.

• Portal: a graphical, browser-based interface for data discovery and visualization.
• Notebook: a Jupyter lab interface for scripted data access and analysis.
• API: remote access based on IVOA Virtual Observatory standards; API stands for Application Programming Interface.

Alert brokers

Alerts are packets of data for time-domain astronomical events (e.g., variable stars, explosive transients, moving objects). Alert brokers are independent software systems that filter and analyze the alert packets, and provide access to them via user interfaces. Alerts are transmitted by Rubin Observatory to alert brokers within 60 seconds of every new image obtained during the night.

For science goals that rely on real-time analysis and follow-up of time-domain events, it is necessary to access alerts via brokers.

Independent Data Access Centers (IDACs)

IDACs are data centers that serve LSST data sets in full or in part, but are not developed or maintained by Rubin staff and are not funded by the Rubin operations budget.

IDACs are typically motivated by one of the following descriptions.

• Serve other data sets, proprietary or public, alongside Rubin data.
• Host specific software, proprietary or public, for analysis of Rubin data.
• Provide hardware or computational resources, such as GPUs, for (re-)processing Rubin data.
• Support a more narrow range of science goals or geographic user base.
