User Query
The User Query (userquery.linea.org.br) is a user-friendly interface for database queries that enables the creation of temporary tables. User-generated tables are managed by MyDB and can be immediately accessed in LIneA's JupyterHub or from anywhere via the TAP Service. Additionally, if a table contains equatorial coordinates and a column with unique identifiers, it automatically becomes a target list, allowing visualization of corresponding object images in the Target Viewer tool (LSST images for members and DES DR2 images for the general public).
TAP Service¶
The IVOA TAP Service (Table Access Protocol) is a standard that enables access and querying of astronomical databases through SQL language, in a standardized and interoperable way across different services. In addition to the User Query service, public catalogs hosted at LIneA can also be accessed remotely via the TAP Service using TOPCAT or programmatically through the Python library pyvo. Visit the TAP Service documentation on the User Query website for more details on how to use the service.
