WFI Spectroscopic Mode User Guide
The Wide Field Instrument (WFI) on the Roman Space Telescope has a slitless spectroscopy mode, using either a grism or a prism. The WFI Spectroscopic Mode User Guide is maintained by the Roman Science Support Center (SSC) at IPAC.
WFI Spectroscopic Mode User Guide
Documentation on the spectroscopic capabilities of WFI will be maintained by the Roman Science Support Center (SSC) at IPAC.
Resources for the WFI Spectroscopic Mode:
- Roman Science Simulations created by the SSC grouped by instrument,
- Characterization of Nancy Grace Roman Space Telescope slitless spectrometer (grism) (Gong et al. 2020),
- Spectral characterization of the Grism and Prism slitless spectrometers for the Nancy Grace Roman Space Telescope (Bray et al. 2024), and
- the WFI Ground Testing Campaigns and On-Orbit Calibration Plan articles provide additional information about the characterization of the prism and grism.
The Spectroscopic Mode User Guide is under development. More documentation will be available in future RDox releases.
Simulated WFI Spectral Image
Simulated slitless spectroscopic image created to understand the prospects for a high-redshift galaxy survey. The full simulation is described as part of the documentation at the Roman Science Support Center at IPAC.
