REX - Radio Science EXperiment


Organization

The REX dataset contains a total of four data volumes. These volumes are split between the categories of post-launch checkout data and Jupiter encounter data. Each category contains two volumes; one consists of raw instrument data, the other processed.

Directory and File Naming

Each dataset contains the following subdirectories:

  • CALIB: Directory which contains calibration files such as dark and flat-field correction .fits.
  • CATALOG: Directory containing high-level catalog objects.
  • DATA: Directory containing the actual spacecraft science data.
  • DOCUMENTS: Directory which contains information the mission, the spacecraft, the payload, and the data files within this volume
  • DOWNLOAD: Directory containing the entire dataset in gzip'ed form.
  • INDEX: Directory containing ASCII index tables that provide information about each data file in this data set.

The filenames of data files follow the naming convention:

INST_SCRMET_APID_STATE_VER.TYPE

  • INST is the instrument/observation designator.
  • SCRMET is the Spacecraft Receipt Mission Elapsed Time.
  • APID is the Application ID (ApID) of the telemetry data packet from which the data come.
  • STATE is ENG for raw data, SCI for calibrated data.
  • VER is the version number from the Science Operations Center.
  • TYPE is the file type, .FIT for FITS file, .LBL for PDS label.
