Planning a Roman WFI data analysis workflow requires coordinating SOC file exchanges, processing L0-L3 data products, and retrieving data from MAST or IRSA archives. You must be familiar with Roman data formats, GWCS, ASDF, and CRDS.

SOC file exchange involves transferring Roman Space Telescope data products through the Science Operations Center. It requires understanding WFI data formats, ASDF files, and GWCS coordinate systems to ensure proper delivery and ingestion across L0-L3 processing levels.

Romancal and romanisim are core tools for Roman data processing and simulation. You apply romancal to calibrate WFI data products through the pipeline, and use romanisim to generate simulated Roman observations, both relying on ASDF, CRDS, and GWCS.

Yes, GWCS and ASDF are essential for working with Roman Space Telescope data. GWCS handles the world coordinate system transformations for WFI data products, while ASDF is the file format used to store Roman data metadata and calibration reference information from CRDS.

Yes, you can retrieve Roman Space Telescope observations from MAST and IRSA archives. The workflow involves querying these archives for L0-L3 data products, then using tools like romancal and rad to process and analyze the retrieved WFI observations.

To simulate Roman WFI observations, use Pandeia for exposure time calculations and STPSF for modeling the telescope's point spread function. These tools work alongside romanisim to generate realistic simulated data products that match the expected WFI data formats.
