Perform a quick cone search by target name or coordinates
using a default radius (specific to each mission) for a specified
set of data types (default is all).
(Note: this mode currently excludes x-ray and radio missions)
. More search options are available by clicking "more options"
or going to
Perform a string search on target name by selecting the
"Don't Resolve" option. The Kepler, GALEX, and Vlafirst mission
however will be excluded. Blanks are significant, case is not
significant, and wild cards are allowed, but the target
name must include at least one letter. This option is useful
for finding moving targets (e.g., planets).
By not entering a target name or coordinates, one can
display a list which briefly describes the
available MAST missions
for a specified set of data types (default is all).
The information below describes the various search options.
Note: if you already know which data set(s) you are interested in,
(i.e., which mission or survey), you may instead
click the "Mission Search" link at the top of the page
to display a list of links to mission-specific search
click on the mission names shown at the bottom right
of the main MAST page to go to the mission home pages and
select search options available there.
For further assistance,
contact a MAST staff member by clicking the "Contacts" link at the
bottom of the page.
Entering either a target name (to be resolved by SIMBAD
or J2000 coordinates (RA and DEC separated by a comma or Dec sign)
will start a cone search (using default search radii) for available data sets
within MAST. Multiple target names can also be specified with comma
delimiters, but only one set of coordinates can be specified.
Coordinates can be either in decimal degrees or sexigesimal
notation with either blanks or colons separating values.
Valid coordinates include:
10 30 5 -28 30 0
If band/data types are selected, the search will
be restricted to the appropriate MAST missions.
(Note: target searches currently exclude data sets from x-ray
and radio missions).
Currently all missions use 3.0 arcminutes as the default search radius
except for Kepler (0.02 arcmin.), Vlafirst (20 arcmin.), and Galex (6 arcmin.).
Archived data sets have been classified
according to the type of data
and wavelength coverage. The possible
data types include Images, Spectra and Other,
where Other includes time series, polarimetric,
photometric, and astrometric data.
data types and wavelength ranges and then clicking
"Search", will return a list
containing both a summary of each missions data holdings
and a link to the mission home pages. If a particular
target is also specified,
the results page will list the actual data sets
available from each of the selected missions
(Note: target searches currently exclude data sets from x-ray and radio missions).
The wavelength ranges and data types
used in the table are as defined below.
