Planned outage -- MAST Services will be unavailable Tuesday 16 January 2018, 09:00 to 17:00 EST (14:00 to 22:00 GMT) for system upgrades. We apologize for the inconvenience.

User Specified Search Field

You may search on any column listed below. Where reasonable, the table lists the range of valid values or a set of sample values. A description of the column is also given. Note the column "label" is the name displayed on the search forms and in search results. The column "name" is the actual column name in the table and needs to be specified in GET requests.

From a MAST search form, simply select the column "label" in the forms pulldown menu and type in the qualification in the adjacent box. Note that if you specify constraints on the same column in more than one form element, they will all be included in the query and you may not get results you expect. In a HTTP GET request, specify the column "name" in the service request. (See the MAST Services web page for information on sumbitting GET requests.)
