Simulation of a soft-gamma-ray polarimeter on board a microsatellite

The dataset is mainly obtained by simulating the polarimeter using the dedicated Monte Carlo simulation package MEGAlib. The dataset includes all the data generated during the whole simulation process, including the geometric model files of the polarimeter, the orbital background data files, the simulated data files of different particle sources, the data analysis code and the simulation results files. The geometrical model of the polarimeter was constructed using the Geomega package contained in MEGAlib. The Monte Carlo simulation of the polarimeter is implemented using Cosima in MEGlib, which requires the involvement of the particle source and the polarimeter geometry model. During the simulation, simulation data files with the suffix "sim" are generated. The simulated data is reconstructed by the Revan software package for Compton events to produce reconstructed data files with the suffix "tra". Finally, the reconstructed data files were used to perform high-level data analysis using the Mimrec software package to produce simulation results. In addition, some of the results in the article we obtained through the data analysis tool ROOT developed by CERN.
