Kepler Threshold-Crossing Events
A Threshold-Crossing Event (TCE) is a sequence of transit-like features in the flux time series of a given target that resembles the signature of a transiting planet to a sufficient degree that the target is passed on for further analysis.
Interactive Tables
The TCE interactive tables contain parameters for all targets observed by Kepler as Threshold-Crossing Events.

Data Validation
Data Validation (DV) reports come from the Kepler pipeline. A multi-page report is produced for each KIC source with one or more TCEs, and a one-page summary is produced for each TCE.
DV reports and summaries are available from the pop-up bubbles in the TCE and KOI tables. You may also select rows in any of the TCE interactive tables and click on the Generate DV PDF option just above the table.
For some pipeline runs (Q1-Q16 and later), the quarter-stitched light curves
used by DV are available. A description of these light curves and the
files are given on the Kepler Data Validation page. These files are available via the Bulk Download page and can be viewed from the pop-up bubbles in the TCE, KOI and Kepler Stellar interactive tables by clicking on the information icon (
) next to an object name.

Q1-Q16 Information
| Tenenbaum et al. (2014) | Paper describing the TCE detection process for Q1-16
NOTE: This paper uses measured statistics on the TCE to filter out likely false positives. For instructions to do the same in the interactive table, see the documentation. Also, see the View Filtered TCEs and View Filtered Long-Period TCEs links in this table to run the ready-made API queries based on the same instructions. |
| View Filtered TCEs | API query that returns all Q1-Q16 TCEs with likely false positives filtered out |
| View Filtered Long-Period TCEs | API query that returns all long-period Q1-Q16 TCEs with likely false positives filtered out. |
