Notes. A robust weighting of 0.5 was used unless indicated. For molecular lines the transition and upper energy levels are also listed. Units are as indicated in the column heading unless otherwise stated. (a) The noise is per channel for line data cubes. (b)The 13 CO has resolved out structure leading to higher noise in channels where there is strong, poorly sampled emission. Line free channels have a noise of 1.76 mJy beam−1 ch−1.
