for Space Telescopes

Abstract

et al., L. Williams et al.), with the red overlays indicating the degree of lensing magnification. Differences in the detailed structure of the models reflect different approaches used by the different teams, while their overall similarity across the cluster field is highly encouraging for their use in determining the properties of lensed background galaxies. The Barbara A. Mikulski Archive for Space Telescopes (MAST) is one of NASA’s premier astronomy data centers, along with the High Energy Astrophysics Science Archive Research Center (HEASARC) and the NASA/IPAC Infrared Science Archive (IRSA). MAST is the primary archive repository for data from several large, active space missions (Hubble, Kepler, XMM-OM and Swift-UVOT), legacy data from past missions (GALEX, FUSE, IUE, EUVE, and others), planned data from future missions, such as James Webb Space Telescope, and all-sky surveys such as VLA-FIRST, GSC and DSS. MAST supports the scientific research carried out by the astronomical community by facilitating access to its collections, offering expert user support and software for calibration and analysis, and providing value-added scientific data products. These include high-level science products (HLSPs) such as mosaics, catalogs, and spectra delivered to MAST by science teams, as well as enhanced products accessible via the Hubble Legacy Archive (HLA). As of March 2014, the total volume of MAST’s data holdings was approximately 296 terabytes (TB), with an average of 18 TB of data downloaded per month. Current MAST news and updates are continuously posted on our main archive sit
