Providing High-Level Value-Added Data to the Community

We will provide the Roman community with effective access to a database (DB) that stores information on transient events, their classifications, and information about potential host galaxies. This will benefit the wider astronomical community by allowing scientists to quickly access intermediate and higher-level data products, bypassing potentially time-consuming tasks such as object classification and light-curve fitting.

We will also provide a RESTful API, along with an interactive web application for user browsing. This will be used to manage our simulated data products. Additionally, in years 4-5, we will ingest Roman time-domain data from commissioning and early science data.

A major aspect of our work in this area is to release value-added catalogs. We will publish curated releases of transient and variable object light curves, spectra, and classifications. we will additionally provide and identified subset of SN Ia as a good starting point for cosmology analysis by the Roman science collaboration efforts. These catalogs will provide clearly versioned sets of data with Zenodo DOIs and be released regularly over the course of the HLTDS which will be specifically available through the Roman archive.
