Data set Version 2.0 The Science RIDs from the October 2018 review have been applied to this ROSINA dataset. Some minor species (CH4, NH3, HCN, H2CO, C2H6, CH3OH, H2S, C2H5OH, OCS, CS2) detected by DFMS were also added to the V2.0 of the datasets. As a result, V2.0 of this CODMAC L5 dataset has been created, using the COPS, DFMS, and RTOF science data from the CODMAC L2 V2.0 (COPS) and CODMAC L3 V2.0 (DFMS and RTOF) datasets. These changes also affect the structure of the PDS files: columns with references to the files used to extract the minor species densities have been added, and therefore the local density and the statistical uncertainty values have been changed. The L3 to L5 conversion of the RTOF data has been slightly improved, leading to more accurate density values. Data set Overview The CODMAC level 5 science data consist in time series (local density) covering the Prelanding phase for the major species H2O, and CO2 for RTOF, and of H2O, CO, O2, CO2, CH4, NH3, HCN, H2CO, C2H6, CH3OH, H2S, C2H5OH, OCS, and CS2 for DFMS. Rosetta was at distances between 20 and 100 km from the comet during this time, except during a close flyby on Feb. 14, 2015. ROSINA was permanently analysing the coma of the comet with the DFMS and COPS sensors, and part of the time with the RTOF sensor (instrument performance permitting), except during wheel offloadings, when the mass spectrometers DFMS and RTOF were in standby, and during orbit control manoeuvres, 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. For calibrated data we refer the user to the level 3 data.
