CCD SPECTROPHOTOMETRY OF CV - V - 3300-9100 ANGSTROM ATLAS FOR 20 FAINT SYSTEMS

A 7 Angstrom resolution, 3300 - 9100 Angstrom spectrophotometric atlas is presented for 20 objects from the Downes & Shara (1993) catalogue of Cataclysmic Variables (CVs). The stars were selected among those li sted as lacking published spectra. As for previous papers in this seri es, the aim is to check the CV status of the objects spectroscopically and to provide absolute spectrophotometry over a wide optical wavelen gth range. For all programme stars UBVRI magnitudes, continuum fluxes at selected wavelengths and integrated fluxes of emission lines are de rived. Among the 20 programme stars, 10 have a CV-like spectrum, 7 sho w F-G-K spectra similar to those of field stars, one is a white dwarf of the DA type, one is a sdB and one has just a sharp H alpha in emiss ion over a cool continuum.
