DATA_SET_TERSE_DESCRIPTION
DATA_SET_DESCRIPTION Data set Overview : On March, 2, 2004, the Rosetta spacecraft was launched towards comet 67P/Churyumov Gerasimenko. Since then the ROSNA sensor has been tested and optimized for flight during several commissioning slots. All data so far from DFMS and RTOF concern either the in flight calibration gas or back-ground outgassing from Rosetta.Because of several uploads of new voltage settings the data cannot be compared between the different commissioning slots, neither in intensity nor in mass scale! The data can be used only for engineering purposes. The only data which can be used to evaluate the background pressure of Rosetta are the COPS data. Scientific data from DFMS and RTOF will only be available when Rosetta reaches the first asteroid. The explanation of the generated data of the ROSINA sensors can be found in the OPERATION_LOGBOOK.ASC Parameters : DFMS and RTOF data contain neutral gas data as well as ion data. The data are raw, uncalibrated data. COPS contain pressure data of the background pressure and of some thruster firings from the nude gauge. Calibration : COPS data are calibrated. However, the calibration factor has been determined for Nitrogen gas, and may not be appropriate for the outgas-sing of Rosetta. Because the main outgassing component is unknown the correct factor to be used is also unknown. DFMS and RTOF data are uncalibrated and will remain uncalibrated because they have no scientific value. Processing : No processing was applied to the data. Coordinate Systems : No coordinate is specified for the data. Software : No software is provided. Media/Format : The standard distribution format for the data is an electronic volume.
