+      SUBROUTINE slDTFR (IHOUR, IMIN, SEC, RAD, J)
+
+     - - - - - -
+      D T F R
+     - - - - - -
+
+  Convert hours, minutes, seconds to radians (double precision)
+
+  Given:
+     IHOUR       int       hours
+     IMIN        int       minutes
+     SEC         dp        seconds
+
+  Returned:
+     RAD         dp        angle in radians
+     J           int       status:  0 = OK
+                                    1 = IHOUR outside range 0-23
+                                    2 = IMIN outside range 0-59
+                                    3 = SEC outside range 0-59.999...
+
+  Called:
+     slDTFD
+
+  Notes:
+
+     1)  The result is computed even if any of the range checks fail.
+
+     2)  The sign must be dealt with outside this routine.
