Notes. The exact central frequency νcentral depends on the adjustment to the assumed vLSR on the dates of observation. Velocity widths are given using νcentral. Due to Hanning smoothing in the correlator, the velocity resolution is 15% broader except for spectral windows (spw) marked *. These were observed in half the maximum bandwidth in order to fit within the frequency sidebands; the original velocity channel width was half that shown, and the additional averaging gives a final velocity resolution which is only 1% broader than the channel spacing. The letters a, b, c, d represent the frequency tunings for the medium and extended configurations; e, f represent the frequency tunings for the compact configuration.
