References and Object Pointers

  • 3,474,235 new object links (pointers) to 1,872 new references
  • 150,000,000 2MASS Point Source Catalog sources from The Two Micron All Sky Survey (2MASS) (Skrutskie, M. F. et al. 2006AJ....131.1163S)

    Fundamental parameters for 471 million sources in the 2MASS Point Source Catalog (PSC) are being integrated into NED using an updated data ingestion and cross-matching pipeline. This release contains the results of cross-matching 150 million sources (32% of the entire catalog) that are located at declination south of -37 degrees. Among these 2MASS PSC sources, 92% are new objects to NED, and 8% have new cross-identifications with prior NED objects, including the fusion of their photometric data into object SEDs. Cross-matching and data fusion for the rest of the catalog is in progress in the Production database, and will be available in a NED update in early 2018.

Photometry

585 new photometric data points integrated into SEDs, including:
  • VIS : VLT fluxes from Metallicity evolution, metallicity gradients, and gas fractions at z ~ 3.4 (Troncoso, P. et al. 2014A&A...563A..58T)
  • RADIO : ATCA fluxes from A Deep Chandra ACIS Survey of M83 (Long, Knox et al. 2014ApJS..212...21L)
  • SUBMM : Planck and Herschel fluxes from The Herschel Virgo Cluster Survey. XV. Planck submillimetre sources in the Virgo Cluster(Baes M. et al. 2014MNRAS.437.3063K)
  • XRAY : Fermi fluxes from Why are some BL Lacertaes detected by Fermi, but others not? (Wu, Zhongzu et al. 2014A&A...562A..64W)
