Abstract This data set contains derived electron and proton flux energies in MeV from the Standard Radiation Environment Monitor (SREM) instrument on the Rosetta spacecraft, which had the primary target of comet 67P/Churyumov-Gerasimenko. These are CODMAC Level 5 derived data, and measure the radiation in the spacecraft environment during the Medium Term Plan 27 period of the EXTENSION 1 mission phase.
Description Data Set Overview = This data set contains SREM omni-directional fluxes in MeV provided at particular effective energies, converted from the equivalent SREM Level 2 CDF products, which are provided in the EXTRAS directory. Note that the CDF processing levels differ from the CODMAC definition used within these PDS data sets. The SREM CDF Level 0 data are equivalent to the PDS CODMAC Level 2 data while the SREM CDF Level 2 data are equivalent to the PDS CODMAC Level 5 data. These data are useful for determining the energetic particle environment experienced by the Standard Radiation Environment Monitor onboard the Rosetta Orbiter. Processing Differential fluxes have first been derived from the 'raw' Level 0 CDF count rate data using a dedicated unfolding technique over pre-defined energies. The unfolding technique is based on the regularized Singular Value Decomposition (SVD) method described in [SANDBERGETAL2012], and in the SREMDC_FINAL_REPORT_V1.0.PDF file found in the DOCUMENT directory. The fluxes have then been rescaled according to cross-calibration studies between fluxes before a rescaling step against selected reference datasets. SEPEM Reference Dataset v2.0 (i.e. GOES/EPS fluxes cross- calibrated with IMP-8/GME) has been selected as reference for proton fluxes, while RBSP/MAGEIS spin averaged datasets were selected as a reference for electron fluxes. As a result of this process, the highest energy flux levels derived for the electron data were not reliable. Thus, it was decided to reject entirely these products in the production of this Level 5 data set. As such, only 10 energy channels are made available for electron fluxes. These are #1-#10 in the table on page 48 of the SREMDC_FINAL_REPORT_V1.0.PDF file, available in the DOCUMENT directory. A quality value is also provided alongside the fluxes, giving recommendations on their use, as described in the table below. FPDO: Flux Proto...

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 [GLASSMEIERETAL2007A]. A detailed description of the mission analysis can be found in the ROSETTA User Manual [RO-DSS-MA-1001], and the flight Operations Plan [RO-ESC-PL-5000]. On its long way to the comet nucleus after a Launch by Ariane 5 P1+ in March 2004, the ROSETTA spacecraft orbited the Sun ...
