File: 00readme.txt Version: NSSDC 3/09/98 JFC 11/07/02 HKH ------------------------------------------------------------------------- This directory includes several data sets from the International Sun Earth Explorer 3 (ISEE 3) spacecraft, which was renamed the Interplanetary Cometary Explorer (ICE) after leaving its L1 Halo orbit in 1982 and entering a heliocentric orbit after a lunar flyby. drwxr-xr-x 2 itm 512 May 1 2002 2_min_merged_mag_plasma drwxrwxr-x 3 itm 512 Nov 7 14:43 energetic_particles_cr drwxrwxr-x 6 msph 512 Aug 9 16:44 magnetic_fields drwxrwxr-x 7 itm 512 Nov 4 09:24 plasma drwxrwxr-x 4 itm 512 Apr 10 2002 traj Directory 2_min_merged_mag_plasma" contains a data set generated at NSSDC from 1-minute magnetic field data, 24-second plasma data, and daily spacecraft position data. Directory "energetic_particles_cr/composition" contains tables of cosmic ray isotope ratios measured by the High Energy Cosmic Ray experiment (HCR) during the ISEE-3 and ICE missions. Directory "magnetic_fields" contains data from the vector magnetometer, with resolutions of 0.16 seconds, 1 minute, 1 hour, and 1 day. Directory "plasma" contains data from the solar wind and fast plasma experiment. Directory "traj/daily" holds daily values for post-1982 heliocentric coordinates of ICE as calculated by NSSDC's Satellite Situation Center (SSC). Directory "traj/hourly" holds spacecraft position at approximately hourly resolution for the lifetime of the spacecraft, taken from the data pool dataset.
