+  Convert geodetic position to geocentric (double precision)
+
+  Given:
+     P     dp     latitude (geodetic, radians)
+     H     dp     height above reference spheroid (geodetic, metres)
+
+  Returned:
+     R     dp     distance from Earth axis (AU)
+     Z     dp     distance from plane of Earth equator (AU)
+
+  Notes:
+     1)  Geocentric latitude can be obtained by evaluating ATAN2(Z,R).
+     2)  IAU 1976 constants are used.
