Example detector output for a single spaxel and the layout of the micro-lens and input fiber array in the telescope focus. The top figure shows both the simulated detector image and that image summed along one axis. The top x-axis gives the velocity offset from the Bragg wavelength corresponding to the pixel values. The figure uses the data for a single spaxel with one multiplexed Bragg grating with Bragg wavelength 1.083 µm and the emission spectrum of the planet. The planet has an absorption feature between the 0 and 50 km s⁻¹ velocity offsets. The bottom figure shows the boundaries of each micro-lens in the micro-lens array with red lines and the fiber positions behind the micro-lens array with red dots. The Airy pattern visible beneath is a perfect Airy pattern at wavelength λ_ref to illustrate the rough position of each fiber.
