Laitinen and S. Dalla. The file Simulation_sets.zip contains files Set_N_AAAA.csv, where N is an integer from 1 to 8, and AAAA is either "scat" or "turb". These files contain simulation data for 8 different simulation sets with two different types of simulations in each. The simulation sets are described in table1.csv, which contains the data in Table 1 of the paper. Further results are given in table2.csv, which contains the data in Table 2 of the paper Set_N_AAAA.csv: - t0: time of the first crossing of 1-au sphere (s) - dt: time between the last and first crossing of the 1-au sphere (s) - theta0: colatitude of the first crossing of 1-au sphere (degrees) - dtheta: difference between the colatitudes of the last and first crossings of 1-au sphere (degrees) table1.csv: - Set: Simulation set identifier (string) - E MeV: proton energy (MeV) - Pol: Unipolar solar magnetic polarity (B+: outwards and B-: inwards pointing field) - vd_theor: Drift velocity calculated at 1 au from theory (km/s) - Sim: Simulation identifier (scat or turb) - Lambda: Parallel mean free path in scat simulations (au) - dB2B2_1au: Relative turbulence variance at 1 au - vd_FL: Median drift velocity obtained from medians of each turbulence realisation drift velocities (km/s) - vd_FL_std: standard deviation of the medians of each turbulence realisation drift velocities (km/s) - table2.csv: - Set: Simulation set identifier (string) - rL_lambda_s: ratio of the particle’s Larmor radius and the breakpoint scale of the slab component of the turbulence - fs_sim: Drift reduction factor obtained from simulations - fs_sim_std: Standard deviation of drift reduction factor obtained from simulations - fs_BAM: Drift reduction factor obtained from theory of Bieber & Matthaeus (1997) - fs_Eng2017: Drift reduction factor obtained from theory of Engelbrecht et al.
