readme for Prognoz-6
This directory contains magnetic field data obtained in the outer
magnetosphere and in the solar wind by Prognoz 6 between 1977/09/26 and
1978/01/22.
The Prognoz 6 satellite was launched 22 September 1977 into an orbit with
apogee of 200,000 km, perigee of 500 km, and an orbital period of 95 hours.
The data were obtained by an SG-70 fluxgate magnetometer provided by
IZMIRAN's Space Magnetic Research Laboratory. The magnetometer had
a range of +/- 60 nT and an accuracy of about 0.3 nT.
It made one vector measurement every 10.24 sec.
Data files contain ASCII records with time information and magnetic field
and spacecraft position data in both GSE and GSM coordinate systems. Each
file has data for one day on day boundaries. A table of start/stop times
of continuous data is provided as prognoz6.tab. The files are named
pYYMMDD.pr6, showing year month, and day of data
