(5:45 - 5:50 and 6:12 - 6:27) Each record contains a single sector's data for each of 17 LEMMS channels. (The CMS telescope was not powered up during the Venus encounter.) 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 Venus (calculated with SPICE kernel data). The z-axis of the coordinate system points along the magnetic field. The x-axis is chosen so Venus 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. All of the data was taken with the telescope perpendicular to the spacecraft spin axis (motor step position = 4). The rates reported are in units of counts/sec. Pitch and phase angles are recorded in radians.

Invalid data are marked by a -1.0 in the rate column of the invalid data.
