Data Flow

Phoenix standard data products are raw and derived products generated in "pipeline" fashion during mission operations using well-understood procedures. Each type of Phoenix standard products is described in a Data Product Software Interface Specification (SIS) document. Definitions of processing levels for science data products are found in Data Processing Level.

In addition to the standard products, special products may be generated by some data suppliers as time and other resources permit. Those special products that are completed and validated in time for a scheduled release to PDS are delivered along with the standard products. PDS will continue to accept special products after the end of the mission as long as they are documented and validated according to PDS standards.

Figure 1 shows the flow of science data products from the Phoenix downlink through mission operations and science team operations to their ultimate delivery to the Planetary Data System. Downlink telemetry is received at Mission Operations at JPL. The JPL Multi-Mission Image Processing Laboratory (MIPL) generates raw data products (EDRs) and some derived data products (RDRs) for the imaging instruments. EDR and RDR products for other instruments will

be generated under the cognizance of the relevant Science Teams. Both MIPL and the Science Teams will transfer their EDR and RDR products to the Science Operations Center (SOC) at the University of Arizona to make them available to other Science Team members.

Complete archive volumes including data products, documentation, and ancillary materials are assembled, validated under Phoenix Project auspices, and then delivered to the designated PDS Nodes. PDS personnel will work closely with science team members to ensure a smooth transfer. Table 1 lists the elements that comprise the Phoenix archives. All Phoenix archive collections are assembled according to designs specified in Archive Volume Software Interface Specification (SIS) documents, which can be found under the "Resources" tab in "Data Set Documents".

When data products have been delivered to the PDS, they are regarded as publicly available. It is made available to the public online through the PDS online distribution system, the Planetary Image Atlas, and in the form of an Analyst's Notebook.
