Overview

VEGA has a consultation software and also exposes a web service to retrieve observation data.

Data extraction

The application has a special module to query the database through the HTTP port of the VegaObs Web Service. All observations with a non empty data status.

The operation does not require special authentication and can be repeated for synchronization.

Data storage

Within the application, the retrieved data are saved to an XML database that is separated from the database of the other data that are extracted from OIFits files. It is planned to merge the two database schema soon.

As a result, for the time being, the pages listing observations for the Vega data set are distinct from the other search pages and provides a very limited search capability.

Notes

The instrument mode is derived from the columns of the database and the description of the instrument.

The database is designed to link observations with publication but this feature is mostly unused at the moment. Also the data status field may not be always up to date.
