urn:nasa:pds:mess-mag-calibrated:data-rtn-avg:magrtnsciavg04355_01 1.0 1.15.0.0 Product_Observational Korth, H. 2021 The table contains the timetags and 3-axis calibrated samples of the magnetic field in heliospheric RTN coordinates in units of nano-Tesla, Br, Bt, Bn. The spacecraft position is identified by radial distance from the Sun, latitude above the ecliptic plane, and azimuth with respect to the Earth-Sun line in the ecliptic plane. The data represent averages from MAG science packets over the interval given in the file name in units of seconds generated on a given day. START_TIME and STOP_TIME correspond to the TIME_TAG values of the first row and last row in the table, respectively. 2021-03-26 1.0 This product, MAGRTNSCIAVG04355_01_V08.TAB, was originally released in 2015 as part of the PDS3 MESS-E/V/H/SW-MAG-4-SUMM-CALIBRATED-V1.0 dataset. The metadata have been migrated to PDS4. The data themselves are unchanged. 2004-12-20T00:02:25.306Z 2004-12-21T00:02:29.122Z Science Calibrated Heliosphere Magnetosphere Fields Magnetic Background MESSENGER Mission urn:nasa:pds:context:investigation:mission.messenger data_to_investigation Magnetometer Instrument urn:nasa:pds:context:instrument:mag.mess is_instrument MESSENGER Host urn:nasa:pds:context:instrument_host:spacecraft.mess is_instrument_host Calibration Calibrator urn:nasa:pds:context:target:calibrator.calibration data_to_target Earth Cruise 1/011988113.292 1/012074516.392 MESS-E/V/H/SW-MAG-4-SUMM-CALIBRATED-V1.0:magrtnsciavg04355_01 data_to_calibrated_source_product 10.17189/1519746 NASA Planetary Data System This is the first version of this product converted to PDS4.

SECOND 5 16 ASCII_Real 6 UTC second associated with the center time of the averaging interval for the magnetic field samples Br, Bt, Bn in each record. TIME_TAG 6 23 ASCII_Real 13 A derived value for the timetag associated with center time of the averaging interval for the Br, Bt, Bn samples in each record. The derived value is created by the following formula: MET + 0.05 * delta_ts + (dt_sample)*(I-1) - latency. MET is the mission elapsed time for the entire science packet. delta_ts is the delta time in seconds between the MET and the first sample in the downloaded science packet. dt_sample is the time between samples in seconds and given by dt_sample = 1/sample_rate where sample_rate is the reported sample rate in samples per second. I is the incremental counter for each data sample in the science packet. I=1 is the first sample in the packet. Latency is the sample rate-dependent delay of the time stamp recording relative to the actual time of observation. NAVG 7 37 ASCII_Integer 6 Number of samples in averaging interval.
