<P>
Since the user is now at the same point discussed in the interactive
procedure, detailed information is not needed here.
<P>
The logfile will contain the results of the fit. If the command has
found difficulties for more than a few percent of the objects,
something is wrong (e.g. wrong PSF parameters). If the statistics
are acceptable the user may wish to display some windows with
<TT>ANALYSE/ROMAFOT</TT> (see above).
Normally in this phase, in order to realise and to correct the ``bad''
windows (NO CONVERGENCY or ``more than ... iterations'') one should
look at them. This is easily accomplished with <TT>ANALYSE/ROMAFOT</TT>
using the commands ``4'', ``S'', ``O''. These commands will give the
windows which did not find appropriate convergence on all the stars,
or ``4'', ``S'', ``I'' to give windows which needed more than <I>n</I>
iterations.
<P>
The user can intervene as described in the interactive procedure.
If needed, fits can be repeated for these windows to have the situation
where all windows have been reconstructed as a sum of a number of
elementary components. To check the quality of such reconstruction,
a further crossing-over from the automatic path to the interactive
path may be done. In fact, <TT>ANALYSE/ROMAFOT</TT> allows the interactive
check of all the windows. To perform the automatic check one can
execute the command <TT>EXAMINE/ROMAFOT</TT>.
