FIG. 2. — (a) Spectral precision as a function of spectral dispersion when considering image noises (green circles), spectral-shift error (red squares), and their overall contributions (black diamonds). (b) Dependence of spectral precision on spectral dispersion under different photon numbers without the background. (c) Dependence of spectral precision on spectral dispersion with different background levels when the spectral signal contains 3000 photons. Note that the iteration number of numerical simulations is 10 000.
