The following figures illustrate the MOS spectral formats. In yellow is indicated the edge of the imaging field of view. The start and end wavelengths are indicated (in nm) below the lines symbolizing the spectra, and the corresponding spectral resolutions are indicated above the lines. 3 layers of spectra are shown for illustration. The dots indicate the object/slit positions.
