Data Set Overview : This dataset contains the plasma electron density derived from electric field mutual impedance spectra measured by RPC-MIP in active modes for EXT3 (ROSETTA EXTENSION 3) mission phase, between 2016/07/01 and 2016/09/30. Derived data collected in this dataset are referred as CODMAC Level 5 products. Data : RPC-MIP plasma electron density is obtained by on-ground analysis of RPC-MIP spectra acquired when RPC-MIP operated in active modes (SDL and LDL). Automatic algorithms have been developed to extract characteristics features from spectra. These features are related to plasma signatures and enabled in certain conditions to derive the plasma frequency and therefore the plasma electron density. Different algorithms have been developed to adapt the different operational modes of the instrument and to account for instrumental limitations (specific to each operation mode). While derived electron density is believed to be of sufficient quality for science use, false detections or misinterpretations cannot be avoided. The user is invited to use these data with caution and always consider quality values associated to density values. A more detailed description of the plasma electron density dataset can be found in the documentation enclosed in the dataset. Processing : Only CODMAC Level 5 data are present in this data set.

Data confidence is nominal, meaning that all data have been validated by the scientific team and found as expected. Furthermore, a record varying quality factor is provided for each derived parameter.
