CoRoT Exoplanet Search Parameter Descriptions
The following is a brief description for the search parameters of the NASA Exoplanet Archive-CoRoT interface page for the CoRoT exoplanet channel. The parameter values for each CoRoT star have been calculated by the CoRoT project and included in the N2-level CoRoT mission products.| Column Description Keyword | Descriptions: |

| Right Ascension | J2000 Right Ascension of star. Examples of valid inputs are 3h 23m 45.6s, 3 23 45.6, 16:56:22, 50.94. |
| Declination | J2000 Declination of star. Examples of valid inputs are -3d 23m 45.6s, 3 23 45.6, 39:23:45, 3.396. |
| Median B Magnitude | B band magnitude as determined in the CoRoT ground program and reported by the mission. |
| Median V Magnitude | V band magnitude as determined in the CoRoT ground program and reported by the mission. |
| Median R Magnitude | R band magnitude as determined in the CoRoT ground program and reported by the mission. |
| Median I Magnitude | I band magnitude as determined in the CoRoT ground program and reported by the mission. |
| Start Date Coverage | Geocentric date of the first measurement in the CoRoT time series light curve. |
| End Date Coverage | Geocentric date of the last measurement in the CoRoT time series light curve. |
| Mean of light curve in B Channel | Average value of the "blue" channel light curve in electrons/second. Note that a star with "blue", "green", and "red" (chromatic) channel light curves will not have a separate monochromatic light curve as monochromatic light curves can be generated from the chromatic light curves. |
| RMS of light curve B channel | Rms dispersion of the "blue" channel light curve in units of electrons/second. Note that a star with "blue", "green", and "red" (chromatic) channel light curves will not have a separate monochromatic light curve as monochromatic light curves can be generated from the chromatic light curves. |
| Mean of light curve in G Channel | Average value of the "green" channel light curve in electrons/second. Note that a star with "blue", "green", and "red" (chromatic) channel light curves will not have a separate monochromatic light curve as monochromatic light curves can be generated from the chromatic light curves. |
| RMS of light curve G channel | Rms dispersion of the "green" channel light curve in units of electrons/second. Note that a star with "blue", "green", and "red" (chromatic) channel light curves will not have a separate monochromatic light curve as monochromatic light curves can be generated from the chromatic light curves. |
| Mean of light curve in R Channel | Average value of the "red" channel light curve in electrons/second. Note that a star with "blue", "green", and "red" (chromatic) channel light curves will not have a separate monochromatic light curve as monochromatic light curves can be generated from the chromatic light curves. |
| RMS of light curve R channel | Rms dispersion of the "red" channel light curve in units of electrons/second. Note that a star with "blue", "green", and "red" (chromatic) channel light curves will not have a separate monochromatic light curve as monochromatic light curves can be generated from the chromatic light curves. |
| Mean of light curve in white light | Average value of the monochromatic light curve in electrons/second. Note that a star with a monochromatic light curve will not have "blue", "green", and "red" (chromatic) channel light curves. |
| RMS of light curve in white light | Rms dispersion of the monochromatic light curve in electrons/second. Note that a star with a monochromatic light curve will not have "blue", "green", and "red" (chromatic) channel light curves. |
| Exposure Time |
Observing cadence of light curve. CoRoT can be configured to observe at the nominal cadence of 512 sec or at the short cadence of 32 sec. If the light curve contains both 512 sec and 32 sec data, the exposure time is reported is mixed and labeled as -1. |
| Number of Points in light curve | Number of data points in light curve. Must be at least one. |
| Mean of light curve | Average value of light curve in electrons/second Calculated by the NASA Exoplanet Archive. |
| 1 Sigma rms dispersion of light curve | 1-sigma root-mean-square dispersion about the median magnitude of the light curve. Must be greater than or equal to zero. Calculated by the NASA Exoplanet Archive. |
| Chi-square about the median light curve value | Reduced chi-square about the median magnitude value of the light curve. Must be greater than or equal to zero. Calculated by the NASA Exoplanet Archive. |
| Number of points in light curve beyond 5-sigma of median value | Number of data points in light curve which are at least 5-sigma away from the median light curve value. Must be greater than or equal to zero. Calculated by the NASA Exoplanet Archive. |
| Fraction of points in light curve beyond 5-sigma of median value | Fraction of data points in light curve which are at least 5-sigma away from the median light curve value. Must be between zero and one. Calculated by the NASA Exoplanet Archive. |
| Color Temperature | Color temperature of the star as determined in the CoRoT ground program from the broad-band photometry. |
| Contamination Factor | Fraction of light [0,1] within the CoRoT photometric aperture which is attributable to stars other than the nominal CoRoT target star. |
| Spectral Type | Spectral type of the star as determined in the CoRoT ground program from the broad-band photometry. |
| Luminosity Class | Luminosity class of the star as determined in the CoRoT ground program from the broad-band photometry. |
