Time span: 1977-10-22 to 1987-09-26
This data set contains plots of 60-s averages of ISEE 1 magnetic field component values (nT) vs time, on microfiche. Each fiche card contains 20 orbits of data, with three plot panels per orbit. These plots are distinct from the ISEE 1 64-s summary plots. The three plot panels each span 24 h, with the panel labeled PERIGEE centered on the perigee of the spacecraft. The panels labeled PRE-APOGEE and POST-APOGEE somewhat overlap the period of the PERIGEE panel and they also display the magnetic field magnitude. Each orbit is completely covered. The coordinates of the PRE-APOGEE and POST-APOGEE panels are GSM. The coordinates of the PERIGEE panel refer to a system with Z in the direction of the local model field (Olson/Pfitzer, 1977), Y azimuthally eastward (and orthogonal to the local model field), and X completing the system. In addition, the Z component is detrended, i.e., the model field value corresponding to the spacecraft position and UT is subtracted from the measured Z component. The data shown on these plots are also available in digital form from NSSDC as data set 77-102A-04Q.
