The following EMMI/SUSI specific defaults are provided (they are copied at
the beginning  of each session from the directory /midas/calib/do) :


        --The default name of the Observation Summary Table is ost.tbl
     
        --A set of defaults keywords to be read from the FITS files and used
          to build the OST is stored in the table emmi_template.tbl. It 
          contains virtually all EMMI/SUSI FITS keywords

        --Default rules for classifying the frames according to their exposure
          type are stored as descriptors in the image template.bdf.

        --The way these classification rules are applied is defined in the
          table EXPTYPE_CLAS.tbl. By default, the resulting classification
          strings are stored in column EXPTYPE of the OST.


        --Default rules for classifying the frames according to their optical
          path are stored as descriptors in the image template.bdf.

        --The way these classification rules are applied is defined in the
          table OPATH_CLAS.tbl. By default, the resulting classification
          strings are stored in column OPATH of the OST.

More details about defaults are given in the windows where they are applied.
