First of all check that you are looking at the right SG tab in the OT, and whether you are dealing with one MOUS of a multi-array SG. For example if you are dealing with a _TC component of a SG which has both _TC and _TE components, it is probably OK if the observations were performed in a configuration too compact to reach the OT requested resolution. Otherwise, it is possible that the original requested SB specs had been further modified by
P2G before observations (due to change requests for example), and hence that the observations do not completely match the original request. There are multiple ways to check that. In the SCOPS-P2G ticket of the project, each change to the original SB is documented (look for comments containing: 'Incremented version to '). If you have advanced privileges in the OT, those comments are conveniently gathered in the 'project notes' - in the proposal tab, click on the proposal title in the left-side column, project notes can be found below 'Main Project Information'. The advanced privileges may be enabled in the OT by going to File, Preferences, Advanced, and clicking on 'Enable privileged operations'. If you cannot have these privileges, you can ask your DRM to send you the project notes. Finally, the exact specifications which were used for the observations can be found in the OT, within 'SG OUS', which is the last component (below Technical Justification) in the SG tree structure. Look in the 'instrument setup' section to look for spectral setup changes
