Extract

Carbon monoxide (12CO) interstellar clouds are widely distributed while clouds of 13CO, HCN, CS and HCO+ are generally more compact. Additionally the molecular lines of the former species tend to be more intense than that of the latter. High resolution and high sensitivity maps of interesting interstellar clouds are, at present, time consuming when a single beam telescope is used. Multiple beam telescopes are therefore required to undertake these mapping tasks during the periods when the precipitable water vapour content of the atmosphere is low; for sites near sea level these periods can be short.
