Pulsar Observation Ingestion

 Requirements: Collection Support: VLA Pulsar Observation

JIRA Ticket: SSA-6377 - Getting issue details... STATUS

Pulsar file ingestion and metadata extraction will proceed similarly to an EVLA SDM ingestion with possible additional (science, ancillary?) products, identified in a metadata.json file.

Binned Imaging Observations

In binning mode there are no additional products. The only science product is the execution block as defined by the SDM. The SDM will contain an additional table, Pulsar.xml which will give the metadata for the scans using binning mode. Scan information is retrieved using a standard SDM approach: Main.xml contains scans and a pointer to a Config Description which contains a pointer to a Data Description which may contain a pointer to an entry in the Pulsar table. If there is no pointer to the Pulsar table in the Data Description, binning mode was not used for that scan.
