WebNIRSpec's IFU can obtain spatially resolved imaging spectroscopy of a contiguous 3" × 3" area on the sky. To achieve this, the IFU uses specialized optics to reformat the spatial field of view and direct light to the spectrograph optics, which are shared with the multi-object spectroscopy (MOS) and fixed slits (FS) spectroscopy observing modes. WebThe JWST IFUs. JWST has 2 IFUs: the MIRI medium resolution spectrometer (MRS) provides R ~ 1,500–3,500 spectroscopy from wavelengths of 4.9 to 27.9 μm over a contiguous field of view up to 6.6'' × 7.7'' in size, while NIRSpec provides R ~ 100, 1,000, and 2,700 spectroscopy from 0.6 to 5.3 μm over a contiguous field of view 3" × 3" in size. iot python githubWebMay 12, 2024 · NIRSpec fixed slit spectroscopy.

"WebThe fixed slits are always open and, therefore always appear in MSA science mode exposures. Pointers also show zero-order images of the right spectral slitlets—these zero-order slit images are seen in the medium resolution (R ~ 1,000) spectral configurations and appear on detector NRS1.
