Spectral range of the Spectrograph

Blue spectral range:

The total wavelength range is 3738 - 5748 Å. The wavelength ranges of each order are listed here. Before 20 May 2015 the wavelength range was 3790 - 5745 Å and the wavelength ranges of each order are listed here.
In the lower two Figures, one can see an example of a spectrum for this wavelength range taken with the HEROS spectrograph and reduced with the automatic standard reduction pipeline.
