General description: Image of the spectrum for a particular plate, MJD, and fiber, in PNG format. The image is smoothed at 100 km/s (observer frame) resolution. Major emission lines (blue) and absorption features (red) are labeled. The (unsmoothed) 1-sigma uncertainties are shown as a grey band. Areas which should be entirely masked are shown in vertical grey bands (that is, are assigned infinitely large error bars). Above the spectrum are shown identification information, targeting information, any spectroscopic pipeline warnings, as well as the derived redshift and classification. A thumb-nail image is also provided, and in this directory there is an index.html file that will display a web page of all the thumb nails, with links to the full images.
