K2 Data Search Help

Use the K2 Data Search and Retrieval Search form to search the K2 archives by object name (resolved to coordinates), position, observation date, EPIC ID, etc., and retrieve data. Note the current interface uses a table based on a combination of EPIC, the K2 Target Catalog, and an internal Science table generated from data extracted from FITS file keywords.

K2 ID

K2 catalog ID. A sequential number assigned by Kepler project to uniquely identify K2 targets (as defined in the EPIC and Customized Aperture file list).
Range of current observations is 200000811 to 229228998.

Investigation ID

ID assigned by the Kepler project describing GO observing programs. Note that for this particular field, wild cards are automatically added before and after the user-specified input. For example, entering "GO001" will query for all IDs containing the string "GO0001".
examples: GO0001, GO0001_GO0032

2MASS ID

2MASS catalog ID, a sexagesimal, equatorial position-based source name in the form: hhmmssss+ddmmsss[ABC...] included in the KIC)
examples: 19065536+3756395

Target Type

Target type
examples: LC (long cadence) or SC (short cadence)

Object Type

Type of object based on EPIC categories ("star" or "extended") plus categories and target names assigned to the Custom Aperture observations (e.g., extended.M35). Entries with an asterisk (i.e., '*') indicate subtypes are available. From the search form, a 'subtype' form element will appear showing a pulldown menu of subtypes to refine searches. Note wildcards are added before and after the user-specified value so entering a category like "extended" will also find extended.M35.

Subtype

Subtype of object based on the categories of Custom Aperture observations assigned by the Kepler project, and (for exoplanet host stars) the K2 planets table. On the K2 search form, this initially-hidden form element is displayed based on the user-selected Object Type.

Kepler Magnitude

Kepler-band magnitude
range 2.98 to 25.

Campaign

A number indicating the campaign in which the exposure was made. The numbers range from 0 to 8, with campaigns 9a and 9b designated as 91 and 92, and campaigns 10a and 10b to be assigned numbers 101 and 102. Entering numbers 9 or 10 will return both subsets. Note targets may appear in more than one campaign.
