+c      Compute the Parameters of the SSO scheme as described in
+c      LOTT & MILLER (1997) and LOTT(1999).
+c      Target points are on a rectangular grid:
+c      iim+1 latitudes including North and South Poles;
+c      jjm+1 longitudes, with periodicity jjm+1=1.
+c      aux poles.  At the poles the fields value is repeated
+c      jjm+1 time.
+c      The parameters a,b,c,d represent the limite of the target
+c      gridpoint region. The means over this region are calculated
+c      from USN data, ponderated by a weight proportional to the 
+c      surface occupated by the data inside the model gridpoint area.
+c      In most circumstances, this weight is the ratio between the
+c      surface of the USN gridpoint area and the surface of the
+c      model gridpoint area.
