MESSENGER EPPS EPS Raw Pulse Height Data Collection
Uncalibrated Pulse Height Analysis data in binary table format. The PHA EDR format was changed by FSW6 on 8/18/2008. -
collection:
MESSENGER MAG Raw Science Header Information Data Collection
Captures the instrument state (health and mode) as reported by the science packet. This information only changes on packet boundaries so it is kept in a separate EDR, minimizing repetition of information. Each row in the Science Header EDR corresponds to the information extracted from one science packet. -
collection:
MESSENGER MAG Calibrated RTN Coordinates Science Data Collection
Calibrated 3-axis magnetic field samples in Radial-Tangential-Normal (RTN) coordinates. The spacecraft position is given by the radial distance from Sun center, northward latitude above the instantaneous ecliptic plane, and azimuth angle of the spacecraft in the instantaneous ecliptic plane with respect to the Earth-Sun line, positive in direction of the Earth's orbital motion. The data are tagged with latency corrected UTC and MET time stamps. The RTN CDR is derived from the Science EDR. -
collection:
MESSENGER EPPS EPS Calibrated Pulse Height Data Collection
EPS calibrated Pulse Height Analysis data in ASCII table format. The lack of priority groups after the FSW6 load on 8/18/2008 means the weight and group columns of the data are not meaningful after that time. -
collection:

collection:
MESSENGER MAG Time-Averaged Calibrated RTN Coordinates Science Data Collection
Time-averaged spacecraft position and calibrated 3-axis magnetic field samples in Radial-Tangential-Normal (RTN) coordinates. The spacecraft postion is given by the radial distance from Sun center, northward latitude above the instantaneous ecliptic plane, and azimuth angle of the spacecraft in the instantaneous ecliptic plane with respect to the Earth-Sun line, positive in direction of the Earth's orbital motion. The data are tagged with latency corrected UTC and MET time stamps at the center of each interval. The RTN RDR is derived from the Science CDR for this coordinate system with time averages computed within 1, 5, 10, and 60 s intervals. -
collection:
MESSENGER MAG Low-Rate Header Information Data Collection
MAG instrument state (health and mode) as reported by the LRHK packet. This changes only on packet boundaries so it is kept in a separate EDR, minimizing repetition of information. Each row in the LHRK Header EDR corresponds to information extracted from one LHRK packet. -

MESSENGER MAG Alternating Current Data Collection
Contains alternating current (AC) level values at the commanded sample rate. To conserve telemetry the vector sampling will usually be less than the maximum rate, 20 sample/s. To provide a record of the amplitude of fluctuations for frequencies higher than 1 Hz, an AC amplitude is calculated from the internally sampled 20/s data for the sensor axis commanded as the AC_AXIS. Thus, in addition to the vector samples data, a 1 Hz to 10 Hz bandpass average amplitude is evaluated for the commanded sensor axis, selected by command, and recorded as a log AC value with a 4-bit mantissa of the four most significant non-zero bits and a 4-bit power of two exponent of the 4th (least significant) bit of the mantissa. This is called the logAC value. It is created once per second and saved for telemetry at that rate or at the commanded science rate, whichever is less frequent. -
