Besides the choice of the source's size (point source or extended source) the observer can select one out of three different types of spectra:
  1. Model spectrum (stellar, galaxy or uniform template)
  2. Blackbody spectrum
  3. Gaussian-shaped emission line
In imaging mode the stepping of the spectra is 0.5 nm. This stepping is adjusted to the spectral resolution in spectroscopic mode.
