 Spectra and postage stamp images of the 42 member
    galaxies.  Wavelength in &#197;ngstrom on the horizontal axis and
    flux in 10<sup>-19</sup>&nbsp;erg&nbsp;s<sup>-1</sup>&nbsp;&#197;<sup>-1</sup>&nbsp;cm<sup>-2</sup>.
    Uncertainties caused by background noise are indicated by the
    underlying filled grey spectra.  As the flux calibration of the
    GOODS spectra is not very accurate (<a href="/articles/aa/full_html/2009/35/aa09964-08/aa09964-08.html#van06">Vanzella et&nbsp;al.  2006</a>) but the absolute
    flux level of these spectra seem systematically higher than the
    GMASS spectra (for the same magnitudes), they have been divided by
    a factor two.  The origin of the spectra is plotted: GMASS (Kurk
    et al., in prep.) or GOODS (<a href="/articles/aa/full_html/2009/35/aa09964-08/aa09964-08.html#van06">Vanzella et&nbsp;al.  2006</a>), the GMASS identification
    numbers, and the spectroscopic classes (see text).  Robust
    (tentative) spectral features are shown by solid (dashed) lines
    with numbers (see below).  The postage stamps are constructed from
    the HST/ACS observations in the <I>B</I>, <I>V</I>, and <I>I</I> bands, convolved
    with a Gaussian kernel.  Indicated are the morphological class (on
    the left) and the <I>z</I> magnitude (on the right).  The spectra are
    sorted on <I>z</I>-<I>J</I> colour, starting with the reddest galaxies.  The
    numbers for the spectral features refer to: (1)
