This directory provides access to energetic particle data from instruments flown on many planetary, heliocentric and geocentric spacecraft by the Theoretical and Applied Space Physics Division, Skobeltsyn Institute of Nuclear Physics, Moscow State university (TASPD SINP MSU). The data were prepared with partial support from NASA (NAG5-4645) by Dr. Nikolai Pavlov of TASPD. Comments and questions may be directed to him at nnpavlov@taspd.npi.msu.su. Copies should also be sent to Natalia Papitashvili at GSFC SPDF, E-mail: natalia.e.papitashvili@nasa.gov. This directory includes documentation files prepared by Dr. Pavlov: COMMON_INFO.TXT (general information common to data from all spacecraft), LOW_NOISE.TXT (how "low noise" data sets were derived), RAH_TO_HGI.TXT (conversion between coordinate systems), SC_COORDINATES.TXT (description of coordinate systems used) The directory also provides subdirectories for the individual spacecraft from deep space or lunar or planetary orbits: LUNA-17,19,21,22 VEGA-1,2 MARS-2,4,5,7 PHOBOS-2 VENERA-2,3,4,5,6,7,8,9,10,11,13,14,16 ZOND-1,2 and near Earth: COSMOS-900 Each such subdirectory has ASCII data files, spacecraft-specific documentation files (s/c_descr.txt with "s/c" being the individual spacecraft names), a trajectory file, and a GIF file with overview plots. ------------------------------------------------------------------ Related data and directories: SPDF Data and Orbits Services -------------- SPDF Contact: Natalia Papitashvili , Please acknowledge NASA's Space Physics Data Facility for data usage.
