1. To start the scanning session with ESPACE type "espace".
   The prompt  espace>  has appeared and the commands can now be
   typed in:
    espace> exec ana_1416.kumac   ( to start analysis)
           .
           .
           .
           .
    espace> 'number of' histograms saved to disk  ( message you get at the end)
    espace> quit                                     (to exit ESPACE)

    The more detailed story:
    ------------------------
    When starting the macro ana_1416.kumac, the user can specify several
    parameters (default value indicated with *):

    ----------------------------------------------------------------------
    parameter   value    comment
    ----------------------------------------------------------------------
    scint     on ,off*    If 'on' S1, S2 histograms are saved
    gas       on, off*    If 'on' Gas Cherenkov histograms are saved
    shower    on, off*    If 'on' shower and preshower histograms are saved
    vdc       on ,off*    If 'on' VDC histograms are saved
    vertex    on*,off     If 'on' parameters of the vertex in the detector hut
                          and target are saved
    loop      on*,off     If 'on' ESPACE will analyze 1000 events and write
                          the histograms to disk. A prompt will appear asking
                          how may more should be analyzed and added to the
                          histogram.
    optimize  on , off*   If 'on' data is being accumulated to be used later
                          in an optimization procudure.
    opt_var               variable to be optimized
              adc*        scintillator S1, S2 pedestals
              beta        scintillator time offsets, time walk, c
              tzero       VDC time offsets
              drift       VDC electron drift velocity
              tdc_diff    VDC t-x lookup table
              dp_kin      momentum aberrations
              angle       reconstructed target angles

    If one wants to have something else than the default values, changes
    can be made as follows:
    espace> exec ana_1416.kumac optimize=on opt_var=beta loop=off scint=on 

2. To view and/or print the histograms you need to run paw++. 
      
3. In paw++:
   - go to the window "main browser" and click on "hbook"
   - double click on "ana_1416.hbook" file
   - click on "macro"
   - double click on "ana_1416.hbook" file (ana_1416.hbook.kumac)
   - double click on "macro" directory
    * If you want printouts go now to the "executive window" and in 
      the "input pad"  type :
        fortran/file 66 ana_1416.ps  (return)
        graphics/metafile 66 -111              (return)  *
   - double click on "????.plot.kumac" files one by one to plot
     the histograms. Remember that only histograms of those detectors
     exist that were specified 'on' in the ana_1416.kumac parameters.
    * if you chose the printout option close now the ps file by typing in
      the "input pad":
         fortran/close 66   (return)         *
