This directory provides access to the following files: m2_ks-18-4m.dat - data on particles measured with the instrument KS-18-4M on the spacecraft MARS-2 + its trajectory in HGI system; ma_ks-18-4m.dat - almost half of the same data but for the period when the spacecraft is in the Mars orbit + its trajectory in HGI system; mb_ks-18-4m.dat - remained after part of the data for the period when the spacecraft is in Mars orbit + its trajectory in HGI system; m2_ks-18-4m.gif - overview plots, all in one; m2_descr.txt - detailed documentation; m2_coord.trj - trajectory of MARS-2 in two coordinate systems. Subdirectory /lownoise contains the same measured data as the file m2_ks-18-4m.dat but in its extra-rectified variant. See general explanations in low_noise.txt. Common important information on all data sets from TASPD SINP MSU, is placed in the file common_info.txt in upper-level directory.
