class_docstr: Class implementing the EPS-SG-A1 MWS L1b Filehandler.
  
  This class implements the European Polar System Second Generation (EPS-SG)
  Microwave Sounder (MWS) Level-1b NetCDF reader.  It is designed to be used
  through the :class:`~satpy.Scene` class using the :mod:`~satpy.Scene.load`
  method with the reader ``"mws_l1b_nc"``.
