This utility is designed to allow users to
verify the existence of MAST data sets AND to display
the name to be used in astrophysical publications.

This section describes the allowed parameters.
It is intended that the user will enter EITHER
a data set name (or a comma-separated list of names),
OR a file of names to be uploaded. If both fields are
entered, the data set name values will be used by default.
Note: parameters may be specified using either a GET or a POST

For HTML, the results are shown in a table following the search form.
For CSV, a separate page is displayed showing just column headings and
columns of results. For Excel spreadsheet format, results may be displayed

If the input file name is recognized as coming from a specific
project, then the mission name is listed here.
It does not necessarily mean the file exists, only that the data set name
resembles that used by a particular MAST mission.
If no mission can be connected to the input data set, a "-" is shown.
If the file is located in a mission database table, it is listed as "yes".
If a particular mission was indicated, but the entry was not found in that
particular database, "Not Found" is shown. Otherwise, the value is set to
For identified data sets, this column shows the data set name as it would
be specified for an astronomical paper (as specified in the
The name includes the ADEC-approved prefix.
For unidentified data sets, a "-" is shown.
