Abstract This data set present engineering data of the COPS, DFMS and RTOF ROSINA sensors during the Lutetia flyby phase
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. Note on the DFMS data: The user of our level 2 data has to make the conversion from pixel to mass and from ADC counts to ion current himself. In this way he will be aware that the precision is limited and depends on many parameters and he will use the data accordingly. The procedure required to calibrate the DFMS is described in our User manual, Annex D1 (DOCUMENT directory). ROSINA team are currently developing the necessary algorithms, putting emphasis on the quality ...

The spacecraft carries a Rosetta Lander, named Philae, to the nucleus and deploys it onto its surface. A brief description of the mission and its objectives can be found in the Rosetta Science Management Plan [RO-EST-PL-0001] and in papers [GLASSMEIERETAL2007A]. A detailed description of the mission analysis can be found in the Consolidated Report on Mission Analysis [RO-ESC-RP-5500], the ROSETTA User Manual [RO-DSS-MA-1001], and the flight Operations Plan [RO-ESC-PL-50...
