code: private void fillUpSphereDelimiters() {
          logger.debug("Sphere: " + sphere);
          for (int f = sphere; f < 4; f++) {
              HOSECode.append(sphereDelimiters[f]);
          }
      }
docs: If we use less than four sphere, this fills up the code with the missing
  delimiters such that we are compatible with Bremser's HOSE code table.
