      <description>
        The sc2 collection contains ASCII files of coefficients for
        polynomials used to adjust the frequency of the surface echo
        so that it is approximately centered in the 25000 Hz output
        bandwidth. It is assumed that the directly propagating carrier
        was centered in the previous processing step, so this is a
        differential frequency correction. Each sc2 file covers a
        single Magellan orbit in (nominally) 10 second steps and is
        valid for both RCP and LCP. The sc2 files were created in the
        1990's and were reformatted for archive in 2008. File names have
        the form  ydddhhmm.sc2,  where 'y' and 'ddd' are the same as for
        prr files and 'hh' and 'mm' give the start hour and minute,
        respectively, for the data in each file.
