摘要：

Key Odin operational and instrumental features and highlights from our sub-millimetre and millimetre wave observations of H2O, (H2O)-O-18, NH3, (NH3)-N-15 and O-2 are presented, with some insights into accompanying Odin Letters in this A& A issue. We focus on new results where Odin's high angular resolution, high frequency resolution, large spectrometer bandwidths, high sensitivity or/and frequency tuning capability are crucial: H2O mapping of the Orion KL, W3, DR21, S 140 regions, and four comets; H2O observations of Galactic Centre sources, of shock enhanced H2O towards the SNR IC443, and of the candidate infall source IRAS 16293-2422; (H2O)-O-18 detections in Orion KL and in comet Ikeya-Zhang; sub-mm detections of NH3 in Orion KL (outflow, ambient cloud and bar) and rho Oph, and very recently, of (NH3)-N-15 in Orion KL. Simultaneous sensitive searches for the 119 GHz line of O-2 have resulted in very low abundance limits, which are difficult to accomodate in chemical models. We also demonstrate, by means of a quantitative comparison of Orion KL H2O results, that the Odin and SWAS observational data sets are very consistently calibrated.
