Observations with SPIRE Spectrometer before OD189 (19 Nov 2009) have not been made public as the detector parameters before that date were not at their final values. Many observations, even those performed using standard astronomer observing templates (AOT), are at different bolometer settings and although the pipeline can run in principle, the calibration is not adapted for those non-optimal parameters. That is why we cannot release this observation to the public, because people will end up with a nice looking spectra or spectral maps, which are not properly calibrated.
