| The following pictures show spectra of approximately 700 Å width for the same stars. In <color blue>blue</color> (900 lines/nm) and <color red>red</color> (200 lines/nm) there are two spectra shown for each star. The spectra were taken with gratings of 200 and 900 lines per nm, respectively. The spectral resolution in the <color red>red</color> spectrum should be higher by a factor of seven. | The following figures show spectra of approximately 700 Å width for different stars.
