\caption{\label{linelist}Line intensities and identifications in each spectrum.  Rows beginning with a ``+'' indicate that the line is blended with that on the row above.  The quantum numbers given in the ``transition'' column are $J$ except where stated.  H$_2$O transitions are given in the format $J^\prime${}$_{k_a^\prime}${}$_{k_c^{\prime}}$-$J_{k_a}${}$_{k_c}$
