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.)


Column Name Column Label Description Examples/Valid Values Data Type
kepler_name Planet Name Kepler-assigned planet name in form kepler-n[b,c,d..] where n is a sequential number assigned by the project followed by a letter (starting with b) to distinguish planets in multiple planetary systems. example: kepler-7b char
koi KOI Kepler assigned Object of Interest (KOI) number with decimal value indicating planet number. example: 18.01, 377.03 float
kepid Kepler ID Non-unique Kepler ID identifying corresponding star entry in the Kepler Input Catalog. Note multiple planets can be assigned the same kepler ID. range: 2571238 to 12644769 long
kic_ra RA (J2000) Right Ascension in decimal degrees derived from Kepler Input Catalog range: 281.288 to 299.407 double
kic_dec Dec (J2000) Declination in decimal degrees as extracted from Kepler Input Catalog range: 37.85 to 51.76 double
eqt Planet temp Computed planet temperatures are based on an assumption that the planet is in equilibrium with radiation from its star balanced by its own black body radiation, taking into account some reflection of radiation from the planet (albedo). Actual albedo is unknown. The planet temperatures calculated do not take into account atmospheric properties, since these are unknown. If Earth did not have atmosphere, its temperature would be below the freezing point of water. In the case of Jupiter, not only does it have an atmosphere to complicate things, but a significant internal heat source as well. range: roughly 170 to 2000 degrees K float
prad Planet Radius Estimated planet radius (earth = 1.0) range: 1.42 to 19 float
duration Transit duration Duration of transit range: roughly 2 to 10 char
period Period Estimated Planet period in earth days range: roughly 0.8 to 229 float
sma Semi-major Axis Estimated semi-major axis in AU. range: 0.016 to 0.7 float
feh Metallicity Derived Log10 Fe/H metallicity accurate to 0.5 dex. range: -0.3 to 0.34 float
mass Stellar Mass Estimated Stellar Mass (solar = 1.0) range: roughly 0.2 to 1.5 float
stellar_radius Stellar Radius Estimated Stellar Radius (solar = 1.0) range: 0.2 to 2 float
teff Stellar Teff Derived Effective Temperature accurate to 200 K range: 4450 to 6500 degrees K float
logg Logg Stellar Surface Gravity (cm/s2) range: float
kepmag KEP Mag A magnitude computed according to a hierarchical scheme and depends on what pre-existing catalog source is available, SCP, Tycho 2, or photographic photometry, in order of preferred selection. For SCP stars the magnitude is synthesized from the Sloan-like g and r magnitudes according to the following prescription: if one defines 'color' as g - r, then for color less than or equal to 0.8 kepmag = 0.8r + 0.2g, while for color greater than 0.8 kepmag = 0.9r + 0.1g. Empirical measurements for presumed constant stars suggest that the r.m.s. for this quantity is slightly larger 0.02 mags. except for very faint and bright stars. range: 10.97 to 13.7 float
kepoi_name KOI Name Kepler assigned Object of Interest (KOI) name example: KOI-157 char
last_updated Last Update Date of last update. example: 9/8/2011 12:00:00 Note, as with all MAST datetime fields, the following examples are valid date formats when submitting queries: "< Jan 10 2008", "Jul 1 2009 .. Aug 1 2009", "1/1/2008", "2009 Jul 15 14:30:20" char
