ISEE 1 magnetometer 1-min data at CDAWeb

ResourceID
spase://NASA/NumericalData/ISEE1/MAG/PT1M

Description

This data set contains magnetic field component
and magnitude averages every minute, with components given in spacecraft,
GSE and GSM coordinates. Standard deviations in the averages are given,
as are differences between the averages and model field vectors.
Geocentric (GSE and GSM) spacecraft position information is given,
as is ISEE1-ISEE2 separation vector information. ISEE 1 spin vector
direction and ISEE 1 velocity vector information, relative to the
Earth and to ISEE 2, are given. Miscellaneous other parameters are
also given. Data are accessible as plots, lists and files from
CDAWeb, and as CDF files from CDAWeb's ftp area.
