RO-C-ROSINA-2-ESC2

Data set Version 2.0 The Science RIDs from the October 2018 review have been applied to this ROSINA dataset. The ROSINA team also found corrupted files in the RTOF, DFMS, and COPS science data V1.0 of this dataset, these corrupted files have been removed in the V2.0. The list of these removed files can be found in the REMOVED_L2_V1_TO_V2.ASC file. Some of the DFMS PDS files were missing in the L2 V1.0 and were added them into the V2.0. The COPS science HK order also changed without modifying the structure: the COPS HK table composed by the 5 last standard COPS HK blocks are now in time order, this change is reflected in the latest version of the ROSINA EAICD document. As a result, V2.0 of this CODMAC L2 dataset has been created. Data set Overview Rosetta was at distances between 80 and 220 km from the comet during this time, except during a close flyby on March 28, 2015. ROSINA was permanently analysing the coma of the comet with DFMS and COPS sensors and the RTOF sensor part of the time (instrument performance permitting), except during wheel offloadings when the mass spectrometers DFMS and RTOF were in standby and during orbit control manoeuvers, when all sensors were off. Explanations on the data generation 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 data contains nude gauge pressure values of the combined spacecraft and cometary signal. Calibration COPS data are calibrated. However, the calibration factor has been determined for Nitrogen gas, and may not be appropriate for the the coma composition. For this the data from RTOF or DFMS have to be taken into account. Note on the DFMS and RTOF 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.
