BEFS Field Descriptions
You may submit queries using any of the fields listed below. 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. (See the MAST Services web page for information on submitting GET requests.) If the "Column name" is in italics, it means the table is indexed on that field and queries with that field will run faster. Clicking on "Data Type" entries will display information on search options. When using the "user-specified field" form element on a MAST search form, simply select the column "label" in the forms pulldown menu and type in the qualification in the adjacent box. 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. Note the entries in the table below may be sorted by clicking on the column headings. BEFS Catalog DescriptionLast Update: December 13, 2010
