Example of downloading and processing SDSS spectra
--------------------------------------------------

This is the code used to create the files fetched by the routine
:func:`fetch_sdss_corrected_spectra`.  Be aware that this routine
downloads a large amount of data (~700MB for 4000 spectra) and takes
a long time to run (~30 minutes for 4000 spectra).
