Abstract: |
Discusses the role of a pipeline in the AXAF Science Center Data System. Due to the complexity of the application, a prototyping effort was initiated to evaluate the risks involved with portability, open architecture, error handling/recovery, and distributed processing. Processes in the pipeline are initiated and monitored by a process control application developed using Perl. Currently, the process control application can attach IRAF, IDL, shell scripts, and various third party executables to create a number of data processing flows. An example process flow involves the acquisition of raw telemetry data from a data simulator to an image file. An error logging library was also developed to form the foundation for handling both minor and fatal errors. |
