Data Set Overview : This data set contains Level 4, Version 2 Spectroscopic and Continuum data in the form of table files, taken during the ROSETTA PRELANDING (PRL) phase of the Rosetta mission by the MIRO instrument. The primary target of the data set is 67P/CHURYUMOV-GERASIMENKO 1 (1969 R1) and the data set is calibrated and processed. Spectroscopic data are so-called 'folded' spectra presented on a velocity scale. Continuum data are resampled and averaged to 1-second time resolution. See the MIRO Users Manual for a more detailed description. The most significant changes between Versions 1 and 2 are that this new version adds the 1-second continuum data, and it provides the spectroscopic science data and corresponding geometry information in a single file instead of having separate data and geometry files. These data cover the following periods and activities: Start Time Stop Time Activity (yyyy-mm-ddThh:mm) (yyyy-mm-ddThh:mm) 2014-01-21T00:00 2014-11-18T23:59 ROSETTA PRELANDING Author List : The author list in the CITATION_DESC includes only those persons who worked on preparing this archive dataset for delivery.

These data have passed high-level scientific review and are suitable for general use. Artifacts and errors may remain, however, so users must assess the validity for their specific purpose.
