NED service to query for Objects by Reference Code:
The NASA/IPAC Extragalactic Database (NED) provides a comprehensive fusion
of multi-wavelength data for hundreds of millions of objects located beyond
the Milky Way galaxy.
This service searches NED's master list of extragalactic objects by (19 digit)
journal reference code. It returns object names, positions, and
redshifts if available. It also returns counts of bibliographic references, notes,
photometry, positions, redshifts, diameters, and positional associations.
The Filter Profile Service provides standardized information, including transmission curves and calibration, about astronomical filters. The service is designed to be compliant to the VO Photometry Data Model.
