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.)

kct_sky_group_id_value Skygroup_ID An integer value from 1 to 84 describing the module/channel where the target falls. It's equivalent to the channel number during season 2. The sky group is an integer that groups stars together on the sky depending on which channel they fall on (or near) during season 2. Due to slight asymmetries in the CCD array layout, positions are not perfectly maintainted upon seasonal rotation of the spacecraft. Therefore, there are objects that fall off silicon during season 2 but are on silicon in subsequent seasons. This is especially problematic for Module 13 due to the center gap. Such stars are assigned the sky group corresponding to the other stars that fall on the same channel during other seasons. range: 1 - 84 long

The metric is simulated using a complete end-to-end model of the instrument. It is derived from stellar magnitudes taken from the Kepler Input Catalog.
