Notes. ^(a) The rms measure is taken over a 1 km s^-1 range.
^(b) Uncertainties in the peak temperature and integrated line intensity are dominated by calibration issues. For H₂¹⁶O 1₁₁-0₀₀, 2₀₂-1₁₁, 3₁₂-3₀₃, and ¹³CO 10-9 the uncertainty is 32%. For all other lines the uncertainty is 16%.
^(c) Velocity accuracy better than 0.5 km s^-1.
^(d) A 20% uncertainty in the line widths is due primarily to the component separation.
^(e) The 3 detection limit, for data smoothed to the expected line width (5 km s^-1), is 0.015 K.
