Data Handbook Home
The Data Handbook contains documentation of the data format, data processing, and data access developed by the Roman Science Operations Center (SOC) at STScI. Information related to the Wide Field Instrument (WFI) spectroscopic mode and high-level microlensing exoplanet science will be maintained by the Roman Science Support Center at IPAC.
Data Handbook Table of Contents
Below is a listing of the articles in the Data Handbook that are currently published in RDox.
As data management for Roman continues development before an expected launch date in late 2026, elements of this documentation will be created and/or updated with the latest information. Presently, information related to the Advanced Scientific Data Format (ASDF) file format, low-level uncalibrated and basic detector calibrated data product contents, and access to calibration reference files through the Calibration Reference Data System (CRDS) is available.
In a future update to the WFI Data Handbook, we anticipate adding documentation related to high-level data processing including re-pixelated products and source catalogs.
The Data Documentation Ecosystem
The software and resources described in RDox document often have additional documentation users might find useful. These typically fall into several categories:
- User Guides written specifically for this Data Handbook,
- the external webpages and code repositories where the data or software are available, and
- documentation written by the owners of the service and developers of the software.
Table of Roman Data Resources provides short descriptions and relevant links where available.
