Notes. †: Uncertain *: Only central line peaks for Helix positions East and West presented due to the significant number of overlaid, but resolvable velocity profiles detected Peak line intensities are in units of the main beam temperature (Tmb). Velocities of the lines and their FWHM line width (ΔV1/2) are with respect to the LSR. Integrated line intensity (∫TmbdV) is computed from the intensity over the width of the line. The 1σ formal errors are included for each measurement.
