Notes. Numbers in parentheses are 1 uncertainties in units of the last digits. For non-detections, the upper limit to the integrated intensity (1) and the observed rms are shown. Adopted rest frequencies (MHz) for the 4₀₄-3₀₃, 5₀₅-4₀₄, and 7₀₇-6₀₆ transitions are 83 900.572, 104 874.679, and 146 820.687, respectively, and their corresponding upper energy levels (K) are 10, 15, and 28 (Brünken et al. 2009a). For IRAS 16293-2422, line parameters were obtained for both velocity components (see text).
