SDSS spectra Examples
---------------------
Figure 7.1

A sample of 15 galaxy spectra selected from the SDSS spectroscopic data set
(see Section 1.5.5). These spectra span a range of galaxy types, from
star-forming to passive galaxies. Each spectrum has been shifted to its rest
frame and covers the wavelength interval 3000-8000 Angstroms. The specific
fluxes, :math:`F_\lambda(\lambda)`, on the ordinate axes have an arbitrary
scaling.
