These descriptors are the result of a translation of the FITS keywords following a scheme described in Vol. A, chapter 7 and automatically performed by MIDAS command INTAPE/FITS. For instance, the FITS keyword 'OBJECT' is translated into the MIDAS descriptor 'IDENT', the contents of the keyword 'EXPTIME' is stored into the 7th element of the descriptor 'O_TIME' and the ESO hierarchical keyword 'HIERARCH ESO GEN EXPO TYPE' is translated into the descriptor '_EGE_TYPE' <P> <BR><HR> <ADDRESS> <I>Petra Nass</I> <BR><I>1999-06-15</I> </ADDRESS> </BODY> </HTML>
