The Mikulski Archive for Space Telescopes (MAST) is a NASA funded project to
support and provide to the astronomical community a
variety of astronomical data archives,
with the primary focus on scientifically related data
sets in the optical, ultraviolet, and near-infrared parts of the spectrum.
MAST is located at the Space Telescope Science Institute (STScI).
Names of objects are passed to a name resolver that associates known object names with sky coordinates. A wide variety of catalog
and common names can be resolved to known objects. Coordinates may be given in a variety of formats; right ascensions must be positive
and southern declinations require a leading negative sign. Examples of valid names and coordinate formats are given below. A search radius
may be specified by appending "r=" and the radius in arcseconds, arcminutes, or degrees (e.g. "r=.2d", "r=5m", "r=1s").
