<P>
The OSP software is a java based application, using the JSkyCat library,
and implementing algorithms to search and validate optimized project masks.
The output is an XML file describing the complete shape of the mask.<BR>
<BR>
Individual slits are specified by their central position on the field,
their length, and their width. These values have to be specified for each slit,
together with the position of the center and the orientation of the field.
The 2D distribution of sources is to be taken from a preexisting image,
real or simulated, or from a given catalogue.<BR>
The OSP will be mainly used during the preparation phases of an observation
(Phase II), and shall allow the observer:<BR>
<UL>
<LI>To perform the selection of objects across the field, manually or
automatically according to predefined criteria on their magnitude,
color or surface brightness, through an input catalog (defined by the user
or downloaded from a catalog server).</LI>
<LI>To overlap a graphic realization of the multi-slit configuration
with an image (real or synthetic). The graphical realization shall indicate
the position, length, width and orientation of each slit, as well as the
extent of the spectra on the detector, and the position of the main sky
emission lines in this wavelength interval. Obviously the orientation is
the same for all slits on a mask.</LI>
<LI>To simulate the result of an EMIR observation with this mask.</LI>
<LI>To validate a mask project by checking its integrity and the non-overlap
of the scientific data on the detector.</LI>
<LI>To create the output XML file containing all the characteristics
needed by the CSU to configure the mask.</LI>
