Requirements: Collection Support: VLA Pulsar Observation
Pulsar file ingestion and metadata extraction will proceed similarly to an EVLA SDM ingestion with possible additional (science, ancillary?) products. Manifest ingestion will be used with a manifest.json file to identify products and a metadata.json file to identify additional metadata to be extracted from the SDM or additional files.
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.
