ddrtFeedCont

• group: EventStream table: <dbase-name> state: ddrtFeed
• group: TPP table: TPP state: ddrtFeed

ddrtFeedCont creates hypoinverse archive files (using dbselect) and exports them to the real-time double-difference systems. The export mechanism can be email, scp to remote location, or two-step copy to a local directory such as the input directory for the sendfileII program.

There are two instances of ddrtFeedCont running on the active post-proc system. One handles new events from the EventStream-<dbase-name>-ddrtFeed stream-state. The other handles events that have been finalized, in the TPP-TPP-ddrtFeed stream-state. These two instances work in the /home/ncss/dertFeed/prelim and /home/ncss/ddrtFeed/final directories, respectively.

To qualify for submission to the ddrt systems, an event must meet the following criteria:

• be of type eq (earthquake)
• be in the NC geographic region
• be an active event; i.e. not deleted from the catalog

Events which do not meet the above criteria will have a delete message generated for them. This is useful for reviewed events whose properties previously qualified it for ddrt but now need to be removed from the ddrt catalog.

Events which have been deleted from the catalog normally are processed by the companion program ddrtDeleteCont.
