<P>
This command selects one subframe from the original frame and generates
an artificial image identical to the primitive but with the quoted window
added at given positions.
<P>
If this window contains one stellar image, one is able to determine,
through a new ROMAFOT session, the ability of the procedure to
detect an object and the general reproducibility of the photometry.
A catalogue, similar to that created by <TT>FIND/ROMAFOT</TT>, is generated
by <TT>ADDSTAR/ROMAFOT</TT>. This catalogue contains the positions where the
subarray has been added and the original instrumental magnitudes in order
to allow a ready detection of the differences. Obviously, one single
window can be added in several output positions and different windows are
generally used in input to sample the behaviour of the errors in luminosity.
<P>
The procedure described above results in a multi-reduction of the same
frame, because, after having generated the artificial image, the user
must go through the commands <TT>SKY/ROMAFOT</TT>
