Find here the detailed spectral plots.

The panels span a wavelength region which is indicated at the left and right margins. Tickmarks are plotted at 2 A separation.

Use the wavelength scale plotted on the top part of the plot to browse the spectrum. The red rectangular marks the displayed region. Clicking on the triangles displays the respective next region. You can also jump to any other region. The vertical navigation bar (left) offers object navigation and is linked to the same wavelength region in different targets. All available targets for the same spectral type are offered. Other spectral types can be enabled by selecting their symbol ("Other SpT").

The wavelength scale is corrected to the stellar rest system.

Telluric absorption lines above 5810 A are marked by the blue vertical bars. Their wavelength has been corrected to the stellar rest frame. These lines have been identified in the telluric reference spectra.

The red horizontal broken line marks an estimate of the local stellar continuum. It is calculated by an algorithm which searches the mode of the signal across the wavelength range displayed. This continuum estimator generally works fine but may be wrong in especially crowded regions. In any case it is intended to give some eye guidance only.

The spectra are *not* normalized but on a physical flux scale, with units of 1e-13 erg/s/cm**2/A. This is not true for the telluric comparison stars which have normalized fluxes.
