EXAMINE/ROMAFOT int_tab [hmin,hmax]
This command uses the quality parameters calculated by FIT/ROMAFOT
for each object and allows the user to select a threshold to accept
or refuse the fit. At the moment, two parameters are calculated by
FIT/ROMAFOT: the reduced 
and the semi--interquartile
interval.
EXAMINE/ROMAFOT works on the intermediate table and starts plotting the distributions of these two fit estimators on the graphics terminal or window. A gaussian fit to these two histograms is then performed in order to define the mode and the sigma of the two distributions. At this stage the user can cut the wings to get parameters not influenced by occasional values.
Once the two distributions have been parametrised, a plot of SD versus
SIQ appears. In order to detect the objects beyond n times 
of the distribution in this plot immediately, the mode is marked
on both axes and the scale is in units of sigma. Using the cursor
the user can select objects whose 
exceeds the value
given by the vertical cursor position (x--axis) or objects whose
SIQ exceeds the quantity corresponding to the horizontal cursor
position (y--axis), or both. Commands to perform the operations
are described in the help documentation and can be displayed using
the command ``H''.
Then, ANALYSE/ROMAFOT allows an automatic examination of objects
flagged by
EXAMINE/ROMAFOT using the sequence of commands ``4'',
``S''', ``T'' and ``D''. Again, if completeness is not required, it
is possible just to ignore these objects in the final registration.
After execution of the command EXAMINE/ROMAFOT the user is in a position similar to that which he finds at the end of the interactive path. However, checking is now limited to objects flagged by EXAMINE/ROMAFOT. To do so one has to execute ANALYSE/ROMAFOT using the commands ``4'', ``S'' and ``T'' (appropriate sets). Then, repeat ``D'' to examine the next window with one star flagged and, if that is the case, correct it.
