Magnetotail Proton and Electron Distribution Functions, ASCII


Availability: Data Identified but not Received


This data set contains an ASCII version of the original binary data set (SPMS-00168). This data set consists of magnetotail proton and electron distribution functions, each with "fluxes" at each of 16 azimuthal look directions and 15 energy steps. The "fluxes" are in distribution function units of particles x sec**3 x cm**2. Derived proton densities and flow speeds (Vx, Vy), time, and spacecraft position and distance to the neutral sheet are also given. The data are for the 1978-1983 ISEE era, plus the April-June, 1986, PROMIS peroid. The data were originally provided to NSSDC on 6 VAX binary tapes (272 4-byte words/record). The data are available at

This ASCII data set is also accessible with graphical display and listing capability and with time and parameter subsetting capability at
