+  Projection of spherical coordinates onto tangent plane:
+  "gnomonic" projection - "standard coordinates" (double precision)
+
+  Given:
+     RA,DEC      dp   spherical coordinates of point to be projected
+     RAZ,DECZ    dp   spherical coordinates of tangent point
+
+  Returned:
+     XI,ETA      dp   rectangular coordinates on tangent plane
+     J           int  status:   0 = OK, star on tangent plane
+                                1 = error, star too far from axis
+                                2 = error, antistar on tangent plane
+                                3 = error, antistar too far from axis
