DATA_SET_DESCRIPTION
This data set contains sixteen sector rate data for the energetic particle detector obtained from the LEMMS and CMS telescopes during the time of significant activity during the Earth encounter on day 342, 1990. Data Set Overview : A data file record contains a single sector's data for a particular ' LEMMS or CMS channel. Also included are pitch and phase angles of the particles counted by the detectors. The angles are determined in a coordinate system defined by the magnetic field (magnetic field data provided by Steve Joy) and the position of Earth (calculated with SPICE kernel data). The z-axis of the coordinate system points along the magnetic field. The x-axis is chosen so Earth lies in the xz plane. The pitch angle is the angle between the sector look direction and the z-axis. The phase angle is the angle between x-axis and the projection of the x-axis on the xy plane. During the encounter, the stepper motor was moving from position zero thru five. Steps one through five are reported in this data set. The rates reported are in units of counts/sec. Pitch and phase angles are recorded in radians.
