NIRSpec in IFU Mode; The image shows the spectra of a Spectral Line Calibration Lamp (Fabry-Perot type) imaged onto the 2 detector SCA's. For this the instrument was in IFU/PRISM mode and the illuminated square aperture has been sliced and re-imaged into a long vertical slit which generates a stack of spectra on the detector.
