The MIDAS FITS reader <TT>INTAPE/FITS</TT> provides this functionality. The data probably will contain frames of different exposure type (biases, darks, flat fields, science frames, etc), and possibly obtained with different filters. After the <TT>INTAPE/FITS</TT> command these different frames are stored on disk. <P> <BR><HR> <ADDRESS> <I>Petra Nass</I> <BR><I>1999-06-15</I> </ADDRESS> </BODY> </HTML>
