RO-C-ROSINA-4-ESC1

Data set Version 2.0 The Science RIDs from the October 2018 review have been applied to this ROSINA dataset. Major species (H2O, CO, O2, and CO2) were used producing the V1.0 of the L4 datasets, minor species (CH4, NH3, HCN, H2CO, C2H6, CH3OH, H2S, C2H5OH, OCS, CS2) detected by DFMS were added for the V2.0 of the L4 datasets. As a result, V2.0 of this CODMAC L4 dataset has been created, using the COPS and DFMS science data from the CODMAC L2 V2.0 (COPS) and CODMAC L3 V2.0 (DFMS) 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. Data set Overview 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 all three sensors, except during wheel offloadings, when the mass spectrometers DFMS and RTOF were in standby and during orbit control manoeuvers, when all sensors were off. Explanation on the data generation of the ROSINA sensors can be found in the OPERATION_LOGBOOK.ASC. This volume contains a dataset of ROSINA pressure records of the combined comet and Rosetta spacecraft outgassing during Escort phase 1. The calibration data can be found in the level 3 volume. The volume also contains documentation and index files to support access and use of the data. 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. Calibration COPS data are calibrated. However, the calibration factor has been determined for nitrogen gas, and may truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
