Problem with Kepler and K2 short cadence pixel calibration

A K2 Guest Observer notified the Kepler Science Center in November 2015 of a puzzling difference between the short- and long-cadence calibrated pixel data for a specific K2 target.

After investigation, the problem was traced to an accounting error for the short-cadence collateral smear data. Under some conditions, these data ...

Previous Short Cadence Data Available at NExScI

As previously reported, Kepler Q2--Q16, data release 24, short-cadence data was calibrated incorrectly, making it unsuitable for use in projects requiring high photometric precision. This is described in this erratum. As a service to the community, the NASA Exoplanet Archive has made available the short cadence data that were released ...

Presenting results at AAS that have public appeal? Let us know!

The K2 mission is well into its second year of operations and is routinely producing exciting and significant science from its observations of fields along the ecliptic. The prime Kepler mission also continues to yield scientifically significant results from its four-year-long observations of the Cygnus-Lyra region.

While we consider each ...
