Description:
    The tables give identifications for molecular lines detected in the
    survey of ultracompact HII regions. The survey covers 14 sources:
    G5.89, G9.62, G10.30, G10.47, G12.21, G13.87, G29.96, G31.41, G34.26,
    G43.89, G45.12, G45.45, G45.47, and G75.78. For each source, we
    observed up to ten 1~GHz bands between 200 and 350~GHz, covering lines
    of more than 30 species including multiple transitions of CO isotopes,
    CH_3_OH, CH_3_CCH, CH_3_CN and HCOOCH_3, and sulphuretted molecules.

    The tables give the measured line parameters of observed frequency
    {nu}(obs), peak temperature T_R_^*^ and linewidth {Delta}{nu}_1/2_ for
    each line. Each independent detection of a particular line is given.
    The species, transition, rest frequency and upper level energy
    (E_u_/k) are given for identified lines.

Note (1): *: Molecular lines observed towards G34.26 at offset positions. The
              lines before the break were observed at (0,20) offset from the
              centre position and the lines after the break were observed
              at (20,0) offset from the centre position.
Note (2): This column gives further information about the line in the form of
           one or more codes.
              blend: blended line
           self-abs: self-absorbed line
                sba: line which has a sideband ambiguity
           sl-blend: when it has been possible to extract lines from blends
           Some HCOOCH_3_, C_2_H_5_OH and H_2_CCHCN lines are blends of two or
           transitions of the same frequency and are indicated as such by blend.
                  *: All possibilities for uncertain detections are given, with
                      the most likely indicated by an asterisk.
