The following dictionary defines a Roman WFI Imaging observation with the F062 filter, 1024x1024 imaging subarray (for a similar 3.04s read time to what is expected for Roman WFI Imaging), medium8 readout pattern, and 6 groups; for a 0.001 mJy flat-spectrum point source (in fnu) intended to be observed with a 0.2" aperture.
