WFIRST :Wide Field Infrared Survey Telescope (WFIRST) is the old name of the Roman Space Telescope. Please, see the Roman section.
WFIRST/WFI :The wide field instrument provides the Wide Field imaging and slitless spectroscopic capabilities required to perform the Dark Energy, Exoplanet Microlensing, and NIR surveys.
These are the old curves (2019/05/31). Please, use the updated versions at Roman/WFI
