All MAST catalog holdings are available via Cone Search endpoints. This service provides access to the MAST copy of the VST Atlas: This survey is targeting 4500 square degrees of the Southern sky in five filters (U, V, R, I and Z) to depths comparable to those of the SDSS. This survey is also complemented by near-infrared data from the VISTA Hemisphere Survey. The primary aim is to examine ‘baryon wiggles’ (small-amplitude oscillations observed in the power spectrum of galaxies) by looking at luminous red galaxies in order to determine the dark energy equation of state. Along with this, the VST ATLAS will provide an imaging base for spectroscopic surveys by the VLT. All available missions are listed at http://archive.stsci.edu/vo/mast_services.html.
