This COLUMN is an INTERPRETATION that has been provided at the request of the peer reviewers of this data set (Sascha Kempf and Mihaly Horanyi, as well as at the request of Michael A'Hearn, the director of the PDS Small Bodies Node at the time of delivery of this data set), and against the advice of the Stardust-NExT CIDA Science Team. The gist of the objection of the CIDA team is that a PDS data set is an excellent tool for archiving data, not interpretations, and that by providing such interpreted data users are encouraged to use, and give the same weight to, the interpretations as they would raw data. The proper place for interpretations is in peer-reviewed literature, where uncertainties in each interpretation can be adequately, and properly, addressed and reviewed. The derivation of this ESTIMATE was highly dependent on the quality of the data in this spectrum. It is irresponsible for anyone to use these values without significant understanding and experience in the interpretration of Time-Of-Flight (TOF) mass spectra. Refer to values for keywords DATA_QUALITY_ID and DATA_QUALITY_DESC in PDS label for qualitative assessement of this estimate. The 'a' and 'b' estimated values, listed in the DATA_QUALITY_DESC keyword string, are an interpretation of these data, and characterize this spectrum. Subject to those caveats, here is the description of this column: The values in this column are ***APPROXIMATE*** masses, in units of daltons, for the time-of-flight (TOF) mass lines. The user is directed to the caveats above if they want to use these values in any way."
