            * controlfiles/artscomponents/zeeman/TestZeeman.arts: No change
              done.
              This test case now runs again, after the change below. But there
              is a deviation to reference data of -0.043 K, that is outside the
              set limit of 0.01 K.

              * src/m_zeeman.cc (Part_Return_Zeeman): Added "if(
                temp_lut.size()
                > 0 )", on line819. This fix suggested by Richard.
