<P>
In case the user wants to examine all windows, the command ``4'' should
be used with the option for the automatic analysis of the intermediate
table. Inspection of selected windows (no convergence, more than N
iterations and so on) is also possible.
<P>
Looking at the display, one can see the reasons why the fit has
some problems and can take action. With the command ``C'' one can
delete one component, with ``I'' (or ``J'') one can add one or more
components. With the ``E'' command one can add a hole and with
``G'' one can delete the hole and restore the subframe.
Both ``C'' and ``G'' ask for the component (or hole) to delete.
<P>
Selecting the contribution of one individual component is not an
easy task in crowded windows. The problem can be overcome with
the commands ``P'' and ``T''. After ``P'' one must give the
sequential position of the star to examine in the window: this
flags with ``0'' all the other components disabling their
display. The user is therefore left with only one component on
the screen.
<P>
It must be noted that after the command ``P'', the key ``Q''
always has to be used to restore the window. Otherwise, all
the other stars will be maintained with the ``0'' flag, and
consequently not considered in following operations (registration, fit
and so forth).
<P>
The command ``T'' is complimentary to the ``P'' command since
it adds the ``0'' flag only to the sequential component selected
by the user. ``T'' is also used to restore the
<!-- MATH: $n^{\rm th}$ -->

component.
<P>
If for some reason the window is totally irrecoverable <TT> ANALYSE/ROMAFOT</TT> offers the possibility to start again with
the window. One should delete all the components and holes
with ``C'' and ``G'' and then call the window with ``N''. In
this way the intermediate table is read in <B>input</B> mode
allowing for commands ``S'' and ``R'', not permitted when the
table is read with the ``D'' command.
<P>
A useful feature is the command ``V'' which enables new tables
to be opened, for instance a new frame. This is sometimes used
to look at variables on different frames or at objects with
extreme colour indexes.
<P>
Finally, the command ``@'' allows the substitution of one component
in a window. In principle, this operation could be performed with
the commands ``C'' and ``I''. However, in that case the new component
is appended. With ``@'' the component can be inserted at a given
position of the list. The actual fit is completely independent of
whichever of the two possibilities one chooses; however, since ROMAFOT
attributes names to the stars according to their sequential position,
the two operations produce different names. This could be important
for subsequent procedures. The same is true if one deletes one component
or flags it with the ``T'' command. The result for photometry is
identical since the object disappears in both cases but, in case
of ``T'', the object survives as far as the name is concerned.
<P>
After all the necessary corrections have been carried out, the user
can now select the windows to be fitted by running the command
<TT>SELECT/TABLE</TT>. The selection should be put on the windows
which should be untouched by a subsequent command <TT>FIT/ROMAFOT</TT>.
This command will then fit only the indicated windows. Of course,
to find a satisfactory solution, the loop <TT>ANALYSE/ROMAFOT</TT>
<!-- MATH: $\rightarrow$ -->

Finally, one should run the command:
