On May 10, 2016, NASA verified 1,284 new exoplanets found by Kepler, the single largest finding of planets to date. Get the latest updates on NASA missions, watch NASA TV live, and learn about our quest to reveal the unknown and benefit all humankind. The other products in this category are for advanced users who wish to perform their own pixel-level calibrations starting with the raw data. Inputs:  Raw pixel-level data (i.e., reverse clock data, artifact removal pixels, background pixels, collateral pixels, raw science pixels, raw full-frame images), focal-plane characterization models, and Kepler Input Catalog). The planetary system orbiting Kepler-11, a yellow dwarf star about 2,000 light years from Earth, included six planets. These scrambled TCEs are used to measure the reliability of the planet catalog that enables a measurement of the reliability of the planet catalog, see the TCERT/Robovetter Reliability Metric. This pipelined reduction includes the removal of time-series trends systematic to the spacecraft and its environment rather than the targets. In both cases, in February and March, the Kepler project team was able to revive the vehicle relatively quickly, within two to three days. Documentation: KAM §2.3.3 for file format and keywords, KIH §2.8 for sample images, KDRN for release notes, entire KDCH for data characteristics, and KDPH §5 for pixel calibration. These Vetting Forms for injected transits are useful in evaluating the performance of the Robovetter on this data set. After another first stage burn, the second stage fired to set Kepler on an escape trajectory into solar orbit. Input: Light Curve Files – Nominal Processing. named Kepler 4b, 5b, 6b, 7b and 8b (which NASA announced in January 2010). These particular TCERT Metrics & Dispositions are from Use Case (d)—the result of inverting the presearch-data-conditioned fluxes (i.e., PDCSAP_FLUX, KAM §2.3.1), conducting a transit search (TPS), and evaluating the identified events (DV).

Residential Candidates This infographic explains how NASA's Spitzer Space Telescope can be used in tandem with a telescope on the ground to measure the distances to planets discovered using the "microlensing" technique. Credit: NASA/Ames/JPL-Caltech/T Pyle. The detection efficiency of the Kepler pipeline was investigated with a series of four experiments using pixel-level transit injection. Location: Go to Kepler Mission Summary Page (NASA Exoplanet Archive) and select the TCE or KOI interactive table of choice. The spacecraft was basically a single instrument—a specially designed 3-foot (1-meter) diameter aperture telescope and image sensor array—with a spacecraft built around it. Format: ASCII table (see options under “Download Table” in upper left of header on interactive tables page). Before retiring the spacecraft, scientists pushed Kepler to its full potential, successfully completing multiple observation campaigns and downloading valuable science data even after initial warnings of low fuel. The full set of collected long and short cadences is listed in the KDCH; those processed in each data release are listed in the associated KDRN. These files are also available via the MAST portal when searching for specific targets. Data Releases:  DR9 to DR25, although only DR25 is directly accessible through the end-of-mission archive. Location: Kepler Simulated Data (NASA Exoplanet Archive) These injected light curves are not available in a searchable table to avoid confusion with the nominally processed light curves from Use Case (a). Data from NASA's Kepler Space Telescope constrains the number of nearby Earth-like planets. These reports/summaries can then be viewed from the pop-up bubbles by clicking on the information icon () next to an object name. Definition:   The collateral data files contain the flux time series for the masked and virtual smear columns and trailing black rows surrounding the science portion of each CCD channel (see KIH Figure 25). Due to the modular design, the losses did not impact the rest of the instrument. These particular DV Reports & DV Summaries are from Use Case (b)—the result of injecting simulated planet transit signatures into the calibrated pixel-level data (i.e., the output of CAL) with subsequent processing through the remaining pipeline modules to create light curves (PA/PDC), conduct a transit search (TPS), and evaluate the identified events (DV). Documentation:  These are standard DV products. Input: Light Curve Files—Nominal Processing. These particular TCERT Vetting Forms are from Use Case (a)—the result of nominal end-to-end operations processing of Kepler flight data in an effort to identify real planets in real flight data. Data Releases:  Pre-launch (KIC) and Q1-Q12, Q1-Q16, Q1-Q17 DR24, and Q1-Q17 DR25 (updates). Definition: The first category of occurrence rate products provides estimates of pipeline completeness for use in occurrence rate calculations. Data Releases: Since the reverse clock data are packaged after download from the spacecraft, but not processed, the concept of data release numbers does not apply. The posterior of those chains are provided for each KOI. These particular TCEs are from Use Case (d)—the result of inverting the presearch-data-conditioned fluxes (i.e., PDCSAP_FLUX, KAM §2.3.1), conducting a transit search (TPS), and evaluating the identified events (DV). The other products in this category include empirical completeness results, which provide ground-truth for selected stars, the Kepler PORTs tools, which can be used to generate contour plots, and a discussion of the limitations of the analytic and numerical models based on comparisons with the empirical results. Given that an earlier one failed in July 2012 and that at least three such wheels were needed to accurately aim the telescope, there was anxiety that the mission might be jeopardized. Kepler detected planets by observing transits, or tiny dips in the brightness of a star that occur when a planet crosses in front of the star. 2016, ApJ, 828, 99, Christopher Burke's KeplerPORTs GitHub repository, NASA Kepler KeplerPorts GitHub repository. Format: ASCII (KIC); IPAC table format (updates), Inputs:  Observational data and stellar evolution models, Outputs: Stellar properties for use in Data Validation, the MCMC analysis, and occurrence rate calculations. For each TCE associated with a given target, the DV summary provides a one-page overview of the information contained in the more extensive DV report (Wu et al. These experiments use differing amounts of data processed by different versions of the pipeline. Inputs:  Threshold-Crossing Events (TCE)—pixel-level transit injection, Outputs: TCERT vetting forms – pixel-level transit injection, TCERT metrics and dispositions—pixel-level transit injection. Output: DV Reports & DV Summaries—Pixel-level Transit Injection. Long ago and far across the universe, an enormous burst of gamma rays unleashed more energy in a half-second than the Sun will produce in its lifetime. Documentation: Kepler Archive Manual (KDMC-10008-006), §2.3.10, with additional on-line material at Ancillary Engineering Data Files (MAST).

(In November 2013, this number was revised up to 40 billion). Format: Flat ASCII text file using Robovetter input format, Outputs: Robovetter dispositions yielding planet-candidate catalogs suitable for occurrence rate calculations. These particular KOIs are from Use Case (b)—the result of a supplemental data validation (DV) run. Format: Interactive online or ASCII tables, Inputs:  Robust RMS CDPP, Duty Cycle, Data Span, Effective MES Threshold, and Pipeline Detection Efficiency, Outputs: Completeness contours suitable for use in occurrence rate calculations. This product improved over time, so later releases are preferred. Definition: The co-trending basis vectors (CBVs) are a set of orthonormal basis vectors that represent the correlated features (or systematic trends) in a reference ensemble of light curves for a given quarter and output channel. Outputs: Archived for public use and used by the transiting planet search (TPS) module of the Kepler data processing pipeline to identify potential transit-like events (a.k.a. Kristen Erickson These particular TCERT Metrics & Dispositions are from Use Case (c)—the result of injecting simulated planet transit signatures into the calibrated pixel-level data (i.e., the output of CAL) with subsequent processing through the remaining pipeline modules to create light curves (PA/PDC), conduct a transit search (TPS), and evaluate the identified events (DV). You can also download this page as PDF. Outputs: Used by dynablack to calibrate the target pixel data. The data for Kepler are hosted in two locations: There are over 40 different kinds of data products. The planet is the closest to Earth in size and temperature found yet in data from the Kepler space telescope. These reports and summaries contain a variety of diagnostic parameters that help determine if a TCE is an instrumental artifact, an astrophysical false positive, or a planetary candidate. Kepler leaves a legacy of more than 2,600 planet discoveries from outside our solar system, many of which could be promising places for life. Inputs:  Threshold-Crossing Events (TCE)—Nominal Processing. 115 miles (185 × 185 kilometers) at a 28.5-degree inclination. There is one FITS file per quarter for each long-cadence target; no analogous short-cadence product is available. Documentation: See KSCI-19085-001 for DR24 and KSCI-19101-002 for DR25 (both at Kepler Completeness and Reliability (NASA Exoplanet Archive), Christopher Burke's KeplerPORTs GitHub repository for a software readme file, and Burke et al. Kepler was equipped to look for planets with size spans from one-half to twice the size of Earth (terrestrial planets) in the habitable zone of their stars where liquid water might exist in the natural state on the surface of the planet. The first six sections are broad categories of data, while the remaining sections are individual data products. From the training set, the Autovetter "learns a mapping between attributes and predicted class. Kepler left behind a legacy of more than 2,600 planet discoveries from outside our solar system, many of which could be promising places for life. Format: FITS (see KAM Table 2-1 for file naming convention and KAM Table 2-2 for file version number). Note that no new KOIs were created in the DR25 Supplemental table --- it has the exact same set of KOIs as the end-of-mission cumulative table. The associated light curves (Kepler Simulated Data: NASA Exoplanet Archive) enable the sensitivities of competing pipelines to be compared or characterized. Inputs:  Synthetic transits are spatially distributed using the pixel response function (PRF) and injected into the calibrated pixels (i.e., the output of CAL) for subsequent processing through the photometric pipeline. Only the last two experiments are directly applicable (i.e., DR24 and DR25) to specific versions of the pipeline (i.e., SOC 9.2 and SOC 9.3, respectively) and are available through the archive. Data Releases:  Q1-Q16, Q1-Q17 DR24, Q1-Q17 DR25. Use Case: TCERT Metrics & Dispositions are generated for five different use cases: (a) nominal processing, (b) supplemental data validation (DV), (c) pixel-level transit injection, (d) flux inversion, and (e) flux scrambling. Other astrophysical signals can mimic a transit signal, when either mass measurements or statistical validation reveal that these other possibilities are less than 1% likely, then the planet is considered confirmed and added to this list.
