Phoenix TEGA Data Bundle

This bundle contains Phoenix Thermal Evolved Gas Analyzer (TEGA) data migrated from the PDS3 volume.

The TEGA bundle contains eleven types of data files:

  SC EDR DATA         SCEDR   Thermal scanning calorimetry raw data
  SC RDR DATA         SCRDR   Thermal scanning calorimetry processed data
  EGA EDR SWEEP DATA  EGAEDR  Mass Spectrometer sweep raw data
  EGA RDR SWEEP DATA  EGSRDR  Mass Spectrometer sweep processed data
  EGA EDR HOP DATA    EGHEDR  Mass Spectrometer peak hopping raw data
  EGA RDR HOP DATA    EGHRDR  Mass Spectrometer peak hopping processed data
  LED DATA            LEDEDR  LED Sensor data
  ENG EDR DATA        ENGEDR  TA and EGA engineering raw data
  ENG RDR DATA        ENGRDR  TA and EGA engineering processed data
  MESSAGE LOG         MSGEDR  TEGA message log
  E KERNEL            EKRDR   Experimenter's Notebook

This bundle contains the following collections:

calibration - TEGA Calibration Report.

document_catalog - Original PDS3 catalog files, containing information about the Phoenix mission, spacecraft, its instruments, and useful references. The *ds.cat files contain details 
about the datasets in the archive.

document - Original data product and PDS3 archive volume Software Interface Specification (SIS) documents. While these documents contain useful information about the data products, please 
note they contain references to the original PDS3 volume and its organization. These documents have not been revised to describe the PDS4 bundle structure.

miscellaneous_index - Original PDS3 index of data files. 

data_egaedr - Phoenix TEGA EGA detector currents EDR data
data_eghedr - Phoenix TEGA EGA mass hopping counts EDR data
data_eghrdr - Phoenix TEGA EGA mass hopping mode RDR data
data_egsedr - Phoenix TEGA EGA sweep mode RDR data
data_ekrdr  - Phoenix TEGA events data 
data_engedr - Phoenix TEGA engineering EDR data
data_engrdr - Phoenix TEGA engineering RDR data
data_lededr - Phoenix TEGA LED sensor (oven fill) EDR data
data_msgedr - Phoenix TEGA message log EDR data
data_scedr  - Phoenix TEGA SC oven heating EDR data
data_scrdr  - Phoenix TEGA Scanning Calorimeter RDR data


Each document and data product in this bundle is described by a PDS4 label in a separate file with the same name but with the extension XML. PDS4 labels are XML (eXtensible Markup Language) 
files that conform to the PDS4 Information Model XML schema at https://pds.nasa.gov/pds4/schema/released/. They are best viewed in an XML-aware text editor, and may be used by software 
that can manipulate XML documents.

Note that the PDS4 labels and other PDS4 products are merged with the PDS3 volume such that all the PDS3 files and directories are preserved. Thus, users who want access to the PDS3 labels 
can continue to use them. All data products have been given PDS4 labels with exceptions noted below. 
- Some PDS3 files remain but are not considered part of the PDS4 bundle, e.g. aareadme.txt in the root directory. This file and the others were not given PDS4 labels since they pertain 
mainly to the archive as the original PDS3 volume.
- Files in the extras directory were not given PDS4 labels. They may be migrated at a later date.
